cccad8f9f0 fs/affs: use ERR_CAST
Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)).  The former makes more
clear what is the purpose of the operation, which otherwise looks like a
no-op.

The semantic patch that makes this change is as follows:

29333920a5 Fix remount races with symlink handling in affs
A couple of fields in affs_sb_info is used in follow_link() and
symlink() for handling AFFS "absolute" symlinks.  Need locking
against affs_remount() updates.

dca3c33652 [PATCH] fix reservation discarding in affs
- remove affs_put_inode, so preallocations aren't discared unnecessarily
  often.
- remove affs_drop_inode, it's called with a spinlock held, so it can't
  use a mutex.
- make i_opencnt atomic
- avoid direct b_count manipulations
- a few allocation failure fixes, so that these are more gracefully
  handled now.

210f855963 iget: stop AFFS from using iget() and read_inode()
Stop the AFFS filesystem from using iget() and read_inode().  Replace
affs_read_inode() with affs_iget(), and call that instead of iget().
affs_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.

affs_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.

If affs_bread() fails, the exit path calls mark_buffer_dirty_inode() with a
NULL argument.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
