This is a note to let you know that I've just added the patch titled xfs: inode unlink does not set AGI buffer type to the 3.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: xfs-inode-unlink-does-not-set-agi-buffer-type.patch and it can be found in the queue-3.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From f19b872b086711bb4b22c3a0f52f16aa920bcc61 Mon Sep 17 00:00:00 2001 From: Dave Chinner <dchinner@xxxxxxxxxx> Date: Thu, 22 Jan 2015 09:29:40 +1100 Subject: xfs: inode unlink does not set AGI buffer type From: Dave Chinner <dchinner@xxxxxxxxxx> 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.
