Various intent log items call xfs_trans_ail_remove() with a log I/O
error shutdown type, but this helper historically checks whether an
item is in the AIL before calling xfs_trans_ail_delete(). This means
the shutdown check is essentially a no-op for users of
xfs_trans_ail_remove().
It is possible that some items might not be AIL resident when the
AIL remove attempt occurs, but this should be isolated to cases
where the filesystem has already shutdown. For example, this
includes abort of the transaction committing the intent and I/O
error of the iclog buffer committing the intent to the log.
Therefore, update these callsites to use xfs_trans_ail_delete() to
provide AIL state validation for the common path of items being
released and removed when associated done items commit to the
physical log.

At unmount time, XFS emits an alert for every in-core buffer that
might have undergone a write error. In practice this behavior is
probably reasonable given that the filesystem is likely short lived
once I/O errors begin to occur consistently. Under certain test or
otherwise expected error conditions, this can spam the logs and slow
down the unmount.
Now that we have a ratelimit mechanism specifically for buffer
alerts, reuse it for the per-buffer alerts in xfs_wait_buftarg().
Also lift the final repair message out of the loop so it always
prints and assert that the metadata error handling code has shut
down the fs.

XFS has some inconsistent log message rate limiting with respect to
buffer alerts. The metadata I/O error notification uses the generic
ratelimited alert, the buffer push code uses a custom rate limit and
the similar quiesce time failure checks are not rate limited at all
(when they should be).
The custom rate limit defined in the buf item code is specifically
crafted for buffer alerts. It is more aggressive than generic rate
limiting code because it must accommodate a high frequency of I/O
error events in a relative short timeframe.
Factor out the custom rate limit state from the buf item code into a
per-buftarg rate limit so various alerts are limited based on the
target. Define a buffer alert helper function and use it for the
buffer alerts that are already ratelimited.

The buffer write failure flag is intended to control the internal
write retry that XFS has historically implemented to help mitigate
the severity of transient I/O errors. The flag is set when a buffer
is resubmitted from the I/O completion path due to a previous
failure. It is checked on subsequent I/O completions to skip the
internal retry and fall through to the higher level configurable
error handling mechanism. The flag is cleared in the synchronous and
delwri submission paths and also checked in various places to log
write failure messages.
There are a couple minor problems with the current usage of this
flag. One is that we issue an internal retry after every submission
from xfsaild due to how delwri submission clears the flag. This
results in double the expected or configured number of write
attempts when under sustained failures. Another more subtle issue is
that the flag is never cleared on successful I/O completion. This
can cause xfs_wait_buftarg() to suggest that dirty buffers are being
thrown away due to the existence of the flag, when the reality is
that the flag might still be set because the write succeeded on the
retry.
Clear the write failure flag on successful I/O completion to address
both of these problems. This means that the internal retry attempt
occurs once since the last time a buffer write failed and that
various other contexts only see the flag set when the immediately
previous write attempt has failed.

The inode flush code has several layers of error handling between
the inode and cluster flushing code. If the inode flush fails before
acquiring the backing buffer, the inode flush is aborted. If the
cluster flush fails, the current inode flush is aborted and the
cluster buffer is failed to handle the initial inode and any others
that might have been attached before the error.
Since xfs_iflush() is the only caller of xfs_iflush_cluster(), the
error handling between the two can be condensed in the top-level
function. If we update xfs_iflush_int() to always fall through to
the log item update and attach the item completion handler to the
buffer, any errors that occur after the first call to
xfs_iflush_int() can be handled with a buffer I/O failure.
Lift the error handling from xfs_iflush_cluster() into xfs_iflush()
and consolidate with the existing error handling. This also replaces
the need to release the buffer because failing the buffer with
XBF_ASYNC drops the current reference.
