3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dave Chinner <dchin...@redhat.com>
commit f19b872b086711bb4b22c3a0f52f16aa920bcc61 upstream.
This leads to log recovery throwing errors like:
XFS (md0): Mounting V5 Filesystem
XFS (md0): Starting recovery (logdev: internal)
XFS (md0): Unknown buffer type 0!
XFS (md0): _xfs_buf_ioapply: no ops on block 0xaea8802/0x1
ffff8800ffc53800: 58 41 47 49 .....
Which is the AGI buffer magic number.
Ensure that we set the type appropriately in both unlink list
addition and removal.
