Fixes for 5.10-rc1:
- Make fallocate check the alignment of its arguments against the
fundamental allocation unit of the volume the file lives on, so that we
don't trigger the fs' alignment checks.
- Cancel unprocessed log intents immediately when log recovery fails, to
avoid a log deadlock.
xfs: cancel intents immediately if process_intents fails
If processing recovered log intent items fails, we need to cancel all
the unprocessed recovered items immediately so that a subsequent AIL
push in the bail out path won't get wedged on the pinned intent items
that didn't get processed.
This can happen if the log contains (1) an intent that gets and releases
an inode, (2) an intent that cannot be recovered successfully, and (3)
some third intent item. When recovery of (2) fails, we leave (3) pinned
in memory. Inode reclamation is called in the error-out path of
xfs_mountfs before xfs_log_cancel_mount. Reclamation calls
xfs_ail_push_all_sync, which gets stuck waiting for (3).
Therefore, call xlog_recover_cancel_intents if _process_intents fails.
