Filipe Manana 2525998ac9 btrfs: fix missing last_unlink_trans update when removing a directory 
[ Upstream commit 999757231c ]

When removing a directory we are not updating its last_unlink_trans field,
which can result in incorrect fsync behaviour in case some one fsyncs the
directory after it was removed because it's holding a file descriptor on
it.

Example scenario:

   mkdir /mnt/dir1
   mkdir /mnt/dir1/dir2
   mkdir /mnt/dir3

   sync -f /mnt

   # Do some change to the directory and fsync it.
   chmod 700 /mnt/dir1
   xfs_io -c fsync /mnt/dir1

   # Move dir2 out of dir1 so that dir1 becomes empty.
   mv /mnt/dir1/dir2 /mnt/dir3/

   open fd on /mnt/dir1
   call rmdir(2) on path "/mnt/dir1"
   fsync fd

   <trigger power failure>

When attempting to mount the filesystem, the log replay will fail with
an -EIO error and dmesg/syslog has the following:

   [445771.719681] BTRFS error (device dm-0 state EA): open_ctree failed: -5

The problem is that such a fsync should have result in a fallback to a
transaction commit, but that did not happen because through the
btrfs_rmdir() we never update the directory's last_unlink_trans field.
Any inode that had a link removed must have its last_unlink_trans updated
to the ID of transaction used for the operation, otherwise fsync and log
replay will not work correctly.

btrfs_rmdir() calls btrfs_unlink_inode() and through that call chain we
never call btrfs_record_unlink_dir() in order to update last_unlink_trans.
However btrfs_unlink(), which is used for unlinking regular files, calls
btrfs_record_unlink_dir() and then calls btrfs_unlink_inode(). So fix
this by moving the call to btrfs_record_unlink_dir() from btrfs_unlink()
to btrfs_unlink_inode().

A test case for fstests will follow soon.
