-When we do inode readahead in log recovery, we do can do the
-readahead before we've replayed the icreate transaction that stamps
-the buffer with inode cores. The inode readahead verifier catches
-this and marks the buffer as !done to indicate that it doesn't yet
-contain valid inodes.
-
-In adding buffer error notification (i.e. setting b_error = -EIO at
-the same time as as we clear the done flag) to such a readahead
-verifier failure, we can then get subsequent inode recovery failing
-with this error:
-
-XFS (dm-0): metadata I/O error: block 0xa00060 ("xlog_recover_do..(read#2)") error 5 numblks 32
-
-This occurs when readahead completion races with icreate item replay
-such as:
-
- inode readahead
- find buffer
- lock buffer
- submit RA io
- ....
- icreate recovery
- xfs_trans_get_buffer
- find buffer
- lock buffer
- <blocks on RA completion>
- .....
- <ra completion>
- fails verifier
- clear XBF_DONE
- set bp->b_error = -EIO
- release and unlock buffer
- <icreate gains lock>
- icreate initialises buffer
- marks buffer as done
- adds buffer to delayed write queue
- releases buffer
-
-At this point, we have an initialised inode buffer that is up to
-date but has an -EIO state registered against it. When we finally
-get to recovering an inode in that buffer:
-
- inode item recovery
- xfs_trans_read_buffer
- find buffer
- lock buffer
- sees XBF_DONE is set, returns buffer
- sees bp->b_error is set
- fail log recovery!
-
-Essentially, we need xfs_trans_get_buf_map() to clear the error status of
-the buffer when doing a lookup. This function returns uninitialised
-buffers, so the buffer returned can not be in an error state and
-none of the code that uses this function expects b_error to be set
-on return. Indeed, there is an ASSERT(!bp->b_error); in the
-transaction case in xfs_trans_get_buf_map() that would have caught
-this if log recovery used transactions....
-
-This patch firstly changes the inode readahead failure to set -EIO
-on the buffer, and secondly changes xfs_buf_get_map() to never
-return a buffer with an error state set so this first change doesn't
-cause unexpected log recovery failures.

-When we do dquot readahead in log recovery, we do not use a verifier
-as the underlying buffer may not have dquots in it. e.g. the
-allocation operation hasn't yet been replayed. Hence we do not want
-to fail recovery because we detect an operation to be replayed has
-not been run yet. This problem was addressed for inodes in commit
-d891400 ("xfs: inode buffers may not be valid during recovery
-readahead") but the problem was not recognised to exist for dquots
-and their buffers as the dquot readahead did not have a verifier.
-
-The result of not using a verifier is that when the buffer is then
-next read to replay a dquot modification, the dquot buffer verifier
-will only be attached to the buffer if *readahead is not complete*.
-Hence we can read the buffer, replay the dquot changes and then add
-it to the delwri submission list without it having a verifier
-attached to it. This then generates warnings in xfs_buf_ioapply(),
-which catches and warns about this case.
-
-Fix this and make it handle the same readahead verifier error cases
-as for inode buffers by adding a new readahead verifier that has a
-write operation as well as a read operation that marks the buffer as
-not done if any corruption is detected. Also make sure we don't run
-readahead if the dquot buffer has been marked as cancelled by
-recovery.
-
-This will result in readahead either succeeding and the buffer
-having a valid write verifier, or readahead failing and the buffer
-state requiring the subsequent read to resubmit the IO with the new
-verifier. In either case, this will result in the buffer always
-ending up with a valid write verifier on it.
-
-Note: we also need to fix the inode buffer readahead error handling
-to mark the buffer with EIO. Brian noticed the code I copied from
-there wrong during review, so fix it at the same time. Add comments
-linking the two functions that handle readahead verifier errors
-together so we don't forget this behavioural link in future.

-Subject: [PATCH] Revert "xfs: clear PF_NOFREEZE for xfsaild kthread"
-Message-ID: <1452661968-11482-1-git-send-email-david@fromorbit.com>
-Content-Length: 916
-Lines: 30
-
-This reverts commit 24ba16bb3d499c49974669cd8429c3e4138ab102 as it
-prevents machines from suspending. This regression occurs when the
-xfsaild is idle on entry to suspend, and so there s no activity to
-wake it from it's idle sleep and hence see that it is supposed to
-freeze. Hence the freezer times out waiting for it and suspend is
-cancelled.
-
-There is no obvious fix for this short of freezing the filesystem
-properly, so revert this change for now.
