ee959b00c3 SCSI: convert struct class_device to struct device
It's big, but there doesn't seem to be a way to split it up smaller...

dc8875e107 [SCSI] docbook and kernel-doc updates
- Change title to remove "Mid-Layer" since the doc is about all of the
SCSI layers.
- Use "SCSI" instead of "scsi" in docbook text.
- Use "*/" to end kernel-doc notation blocks.
- A few other minor typo fixes.

911833440b [SCSI] SRP transport: only remove our own entries
The SCSI SRP transport class currently iterates over all children
devices of the host that is being removed in srp_remove_host(). However,
not all of those children were created by the SRP transport, and
removing them will cause corruption and an oops when their creator tries
to remove them.

72e39ea7e0 [SCSI] srp_transport: convert to use supported_mode attribute
srp transport works for target drivers without supported_mode
attribute but it would be better to use it explicitly.

0012fdf986 [SCSI] scsi_transport_srp: remove tgt dependencies
it's better to remove tgt dependencies in srp transport class since
most people want only initiator support.

bfb743740e [SCSI] tgt: move tsk_mgmt_response callback to transport class
This moves tsk_mgmt_response callback in struct scsi_host_template to
struct scsi_transport_template since struct scsi_transport_template is
more suitable for the task management stuff.

62fe88261b [SCSI] srp_transport: add target driver support
This adds minimum target driver support:

- srp_rport_{add,del} calls scsi_tgt_it_nexus_{create,destroy} for
target drivers.

- add a callback to notify target drivers of the nexus operation
results to srp_function_template.

aebd5e476e [SCSI] transport_srp: add rport roles attribute
This adds a 'roles' attribute to rport like transport_fc. The role can
be initiator or target. That is, the initiator driver creates target
remote ports and the target driver creates initiator remote ports.

09345f6505 [SCSI] add srp transport class
This adds srp transport class that works with ib_srp and ibmvscsi.

It creates only /sys/class/{srp_host,srp_remote_ports} and
srp_remote_ports has only "port_id" attribute.

viola:/sys/class/srp_remote_ports/port-0:1# ls
device  port_id  subsystem  uevent
viola:/sys/class/srp_remote_ports/port-0:1# cat port_id
