808cbb68de [SCSI] pm80xx: remove unneeded NULL check
Coccinelle complains about the inconsistent NULL checking on "t".  It
turns out the check isn't needed because we verified that "t" is
non-NULL at the start of the function.

e73823f7a2 [SCSI] libsas: implement > 16 byte CDB support
Remove the arbitrary expectation in libsas that all SCSI commands are 16 bytes
or less.  Instead do all copies via cmd->cmd_len (and use a pointer to this in
the libsas task instead of a copy).  Note that this still doesn't enable > 16
byte CDB support in the underlying drivers because their internal format has
to be fixed and the wire format of > 16 byte CDBs according to the SAS spec is
different.  the libsas drivers (isci, aic94xx, mvsas and pm8xxx are all
updated for this change.

45f0a85c82 PM / Runtime: Rework the "runtime idle" helper routine
The "runtime idle" helper routine, rpm_idle(), currently ignores
return values from .runtime_idle() callbacks executed by it.
However, it turns out that many subsystems use
pm_generic_runtime_idle() which checks the return value of the
driver's callback and executes pm_runtime_suspend() for the device
unless that value is not 0.  If that logic is moved to rpm_idle()
instead, pm_generic_runtime_idle() can be dropped and its users
will not need any .runtime_idle() callbacks any more.

Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle()
routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and
ata_port_runtime_idle(), respectively, as well as a few drivers'
ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has
been returned by the .runtime_idle() callback executed by it.

To reduce overall code bloat, make the changes described above.

f6e984e636 ipr: qc_fill_rtf() method should not store alternate status register
The 'ctl' field of  the 'struct ata_taskfile' is not really dual purpose, i.e.
it is not intended  for storing the alternate status register (which is mapped
at the same address in the legacy IDE controllers) in the qc_fill_rtf() method.
No other 'libata' driver except 'drivers/scsi/ipr.c' stores the alternate status
register's value in the 'ctl' field of 'qc->result_tf', hence this driver should
not do this as well...

364398324c [SCSI] qla2xxx: Fix for locking issue between driver ISR and mailbox routines
The driver uses ha->mbx_cmd_flags variable to pass information between
its ISR and mailbox routines, however, it does so without the protection of
any locks.  Under certain conditions, this can lead to multiple mailbox
command completions being signaled, which, in turn, leads to a false
mailbox timeout error for the subsequently issued mailbox command.

The issue occurs frequently but intermittenly with the Qlogic 8GFC mezz
card during card initialization, resulting in card initialization failure.

It occurs because fc_seq_send can have multiple contexts executing within it at
the same time, and fc_seq_send doesn't consistently use the ep->ex_lock that
protects this structure.  Because of that, its possible for one context to clear
the INIT bit in the ep->esb_state field while another checks it, leading to the
above stack trace generated by the WARN_ON in the function.

We should probably undertake the effort to convert access to the fc_exch
structures to use rcu, but that a larger work item.  To just fix this specific
issue, we can just extend the ex_lock protection through the entire fc_seq_send
path

e6c10b7c5e libfcoe: Fix Conflicting FCFs issue in the fabric
When multiple FCFs in use, and first FIP Advertisement received is
with "Available for Login" i.e A bit set to 0, FCF selection will fail.
The fix is to remove the assumption in the code that first FCF is only
allowed selectable FCF.
Consider the scenario fip->fcfs contains FCF1(fabricname X, marked A=0)
FCF2(fabricname Y, marked A=1). list_first_entry(first) points to FCF1
and 1st iteration we ignore the FCF and on 2nd iteration we compare
FCF1 & FCF2 fabric name and we fails to perform FCF selection.

aa9f8328fc [SCSI] sas: unify the pointlessly separated enums sas_dev_type and sas_device_type
These enums have been separate since the dawn of SAS, mainly because the
latter is a procotol only enum and the former includes additional state
for libsas.  The dichotomy causes endless confusion about which one you
should use where and leads to pointless warnings like this:

drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo':
drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare]

Fix by eliminating one of them.  The one kept is effectively the sas.h
one, but call it sas_device_type and make sure the enums are all
properly namespaced with the SAS_ prefix.

states, so we need to wait for a bit to allow the LLDD
to recover.

39c60a0948 [SCSI] sd: fix array cache flushing bug causing performance problems
Some arrays synchronize their full non volatile cache when the sd driver sends
a SYNCHRONIZE CACHE command.  Unfortunately, they can have Terrabytes of this
and we send a SYNCHRONIZE CACHE for every barrier if an array reports it has a
writeback cache.  This leads to massive slowdowns on journalled filesystems.

The fix is to allow userspace to turn off the writeback cache setting as a
temporary measure (i.e. without doing the MODE SELECT to write it back to the
device), so even though the device reported it has a writeback cache, the
user, knowing that the cache is non volatile and all they care about is
filesystem correctness, can turn that bit off in the kernel and avoid the
performance ruinous (and safety irrelevant) SYNCHRONIZE CACHE commands.

The way you do this is add a 'temporary' prefix when performing the usual
cache setting operations, so

echo temporary write through > /sys/class/scsi_disk/<disk>/cache_type

b90ebc3d5c [SCSI] scsi_debug: fix logical block provisioning support
provisioning map (map_storep) is a bitmap accessed by bitops.

So the allocation size should be a multiple of sizeof(unsigned long) and
also the bitmap should be cleared by using bitmap_clear() instead of
memset().

Otherwise it will cause problem on big-endian architecture if the number of
bits is not a multiple of BITS_PER_LONG.

I tried testing the logical block provisioning support in scsi_debug,
but it didn't work as I expected.

For example, load scsi_debug module with UNMAP command supported
and fill the storage with random data.

        # modprobe scsi_debug lbpu=1
        # dd if=/dev/urandom of=/dev/sdb

Then, try to unmap LBA 0, but Get LBA status reports:

        # sg_unmap --lba=0 --num=1 /dev/sdb
        # sg_get_lba_status --lba=0 /dev/sdb
        descriptor LBA: 0x0000000000000000  blocks: 16384  mapped

This is unexpected result.  Because UNMAP command to LBA 0 finished
without any errors, but Get LBA status shows that LBA 0 is still mapped.

This problem is due to the wrong translation between LBA and index of
provisioning map.  Fix it by using correct translation functions.

cc34a8e663 [SCSI] scsi_debug: clear correct memory region when LBPRZ is enabled
The function unmap_region() clears memory region specified as the logical
block address and the number of logical blocks in ramdisk storage
(fake_storep) if lbpu and lbprz module parameters are enabled.

In the while loop of unmap_region(), it advances optimal unmap granularity
in logical blocks.  But it only clears one logical block at LBA 'block' per
loop iteration.  And furthermore, the 'block' is not pointing to a logical
block address which should be cleared, it is a index of probisioning map
(map_storep).

ac17078ae6 [SCSI] scsi_debug: prohibit scsi_debug_unmap_granularity == scsi_debug_unmap_alignment
scsi_debug prohibits setting scsi_debug_unmap_alignment to be greater
than scsi_debug_unmap_granularity.  But setting them to be the same value
is not prohibited.  In this case, the only difference with
scsi_debug_unmap_alignment == 0 is the logical blocks from 0 to
scsi_debug_unmap_alignment - 1 cannot be unmapped.  But the difference is
not properly handled in the current code.

So this prohibits such unusual setting.

9ed8d3dc5b [SCSI] scsi_debug: call map_region() and unmap_region() only when needed
If the logical block provisioning is not enabled, map_region() and
unmap_region() have no effect and they don't need to be called.

So this makes map_region() and unmap_region() to be called only
when scsi_debug_lbp() returns true, i.e. logical block provisioning is
enabled.

While I'm at it, this also removes meaningless non-zero check for
scsi_debug_unmap_granularity.

Because scsi_debug_unmap_granularity cannot be zero with usual setting:
scsi_debug_unmap_granularity is 1 by default, and it can be changed to
zero with explicit module parameter setting only when the logical block
provisioning is disabled.  But it is only meaningful module parameter
when the logical block provisioning is enabled.

It appears to me that there is a problem with handling of type 1 protection

It is considering a logical block reference tag of 0xffffffff to be an error,
but it is actually valid any time ((lba & 0xffffffff) == 0xffffffff) [for
example, 2TiB-1, 4TiB-1, 6TiB-1, etc.].

I'm going by what's written in 4.18.3 of SBC3, where there doesn't appear
to be any invalid value for the reference tag.

nonintrusive as possible on initiators and targets, and therefore FIP VLAN
discovery occurs in the native VLAN used by the initiator or target to
exchange Ethernet traffic. The FIP VLAN discovery protocol is the only FIP
protocol running on the native VLAN; all other FIP protocols run on the
discovered FCoE VLANs.

If an administrator has manually configured FCoE VLANs on ENodes and FCFs,
there is no need to use this protocol. FIP and FCoE will run over the
configured VLANs.

An ENode without FCoE VLANs configuration would use this automated discovery
protocol to discover over which VLANs FCoE is running.

The ENode sends a FIP VLAN discovery request to a multicast MAC address called
All-FCF-MACs, which is a multicast MAC address to which all FCFs listen.

All FCFs that can be reached in the native VLAN of the ENode are expected to
respond on the same VLAN with a response that lists one or more FCoE VLANs
that are available for the ENode's VN_Port login. This protocol has the sole
purpose of allowing the ENode to discover all the available FCoE VLANs.

Now the ENode may enable a subset of these VLANs for FCoE Running the FIP
protocol in these VLANs on a per VLAN basis. And FCoE data transactions also
would occur on this VLAN. Hence, Except for FIP VLAN discovery, all other FIP
and FCoE traffic runs on the selected FCoE VLAN.  Its only the FIP VLAN
Discovery protocol that is permitted to run on the Default native VLAN of the
system.

[**** NOTE ****]
We are working on moving this feature definitions and functionality to libfcoe
module. We need this patch to be approved, as Suse is looking forward to merge
this feature in SLES 11 SP3 release.  Once this patch is approved, we will
submit patch which should move vlan discovery feature to libfoce.

4a520d2769 proc: Supply an accessor for getting the data from a PDE's parent
Supply an accessor function for getting the private data from the parent
proc_dir_entry struct of the proc_dir_entry struct associated with an inode.

ReiserFS, for instance, stores the super_block pointer in the proc directory
it makes for that super_block, and a pointer to the respective seq_file show
function in each of the proc files in that directory.

This allows a reduction in the number of file_operations structs, open
functions and seq_operations structs required.  The problem otherwise is that
each show function requires two pieces of data but only has storage for one
per PDE (and this has no release function).

 "The highlights this round include:

   - Add fileio support for WRITE_SAME w/ UNMAP=1 discard (asias)
   - Add fileio support for UNMAP discard (asias)
   - Add tcm_vhost hotplug support to work with upstream QEMU

  The biggest changes revolve around iscsi-target refactoring in order
  to support the iser-target driver.  This includes the conversion of
  the iscsi-target data-path to use modern se_cmd->cmd_kref counting,
  and allowing transport independent aspects of RX/TX PDU

0eb43b4bb0 bnx2x, bnx2fc: Use per port max exchange resources
The firmware supports a maximum of 4K FCoE exchanges. In 4-port devices,
or when working in multi-function mode, this resource needs to be distributed
between the various possible FCoE functions.

This information needs to be calculated by bnx2x and propagated into bnx2fc
via cnic. bnx2fc can then use this value to calculate corresponding xid
resources instead of using global constants.

	include/net/scm.h
	net/batman-adv/routing.c
	net/ipv4/tcp_input.c

The e{uid,gid} --> {uid,gid} credentials fix conflicted with the
cleanup in net-next to now pass cred structs around.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN
interface changes by Patrick McHardy in net-next.

An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.

Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first
argument.

Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO
rewrite in 'net-next', mostly overlapping changes.

Thanks to Stephen Rothwell and Antonio Quartulli for help with several
of these merge resolutions.

9936906597 [SCSI] megaraid_sas: Use correct #define for MSI-X capability
Previously we used PCI_MSI_FLAGS to locate a register in the MSI-X
capability.  This did work because the MSI and MSI-X flags happen
to be at the same offsets, but was confusing.

PCI_MSIX_FLAGS_ENABLE is already defined in include/uapi/linux/pci_regs.h,
so no need to define it again.

1fc2b00fba [SCSI] libiscsi: avoid unnecessary multiple NULL assignments
In iscsi_free_task, NULL is assigned to task->sc twice: before and
after kfifo_in invocatoin. Allocating and freeing iscsi_task are guarded
with session->lock, so multiple NULL assignments cause no trouble. But
people reading the source code may be confused.

The second NULL assignment comes from commit:

    3e5c28ad03

It seems that the line after kfifo_in invocation was introduced
accidentally.

ALUA device handler sends STPG command during failover and failback.  Failover
can be optimized by implicit failover (by not to sending STPG command), when 1
is passed as hwhandler parameter in multipath.conf. ex "2 alua 1". We may need
to pass the parameter through module param for alua device handler to optimize
failover if incase retain_attached_hwhandler set in multipath.conf and

But in driver response path, this count was incremented unconditionally,

Request queue count manipulation has to be done in IO path only, keeping

c18b78ede5 [SCSI] qla4xxx: Take E-port out of reset before disabling pause frames
Problem Description:
Disabling pause frames might cause hardware wedging needing a power cycle.
This might happen if the Eport is not initialized and is in reset.

Solution:
Before disabling pause frames ensure that eport is out of reset.

27db682bf0 [SCSI] scsi_dh_alua: fix stpg sense handling
For the stpg_endio path we are not evaluating the sense. The bug
is that

1. The error value is set to -EIO when there is sense, so we hit the first
error check and always return SCSI_DH_IO.

2. h->senselen is set to zero in submit_stpg. It is not later set to
req->sense_len like in the synchrounous exection paths, so we must
check the req->sense_len field.

d9dda78bad procfs: new helper - PDE_DATA(inode)
The only part of proc_dir_entry the code outside of fs/proc
really cares about is PDE(inode)->data.  Provide a helper
for that; static inline for now, eventually will be moved
to fs/proc, along with the knowledge of struct proc_dir_entry
layout.

859d22f9c3 scsi_proc: make proc_scsi_host_open() preallocate a bigger buffer
Some of the ->show_info() instances really spew a lot; it's not a problem
wrt correctness (seq_read() will grow buffer and call the sucker again),
but in this case it makes sense to start with a somewhat bigger one -
they often do exceed one page worth of output.
