Hi Brian,
Here are two inodes on which the xfsaild is looping over & over during
unmount. This captures right from the cp that I started with copying some
files to xfs while the drive was pulled out, later drive was pushed back &
unmount was attempted. Does this give you better picture on the issue?
Please let me know if you prefer to do some other steps in the reproducer.

xfsaild was stuck towards the end like. The inode number varies, some of
which trace-buffer doesn't capture as with too many events, trace-buffer
lost several events.

It will be hard for me to shift to a newer kernel. But if you say we are
left with no options to root cause this issue, I can attempt at this
direction. Pls let me know. Thanks.

So xfsaild is spinning on this inode. It was presumably modified, logged
and flushed to the log, hence it's sitting in the AIL waiting to be
flushed to disk. xfsaild wants to push it to get it flushed to disk and
off the AIL, but it sees it is already in the flushing state as the
flush lock is held.
It's not clear to me why the inode is not removed from the AIL, or
whether that I/O was actually submitted or aborted with an error. The
shutdown involved here most likely affects this one way or the other.
IIUC, the I/O completion should eventually release the flush lock and
remove the inode from the AIL. A complete trace log of the entire
reproducer might shed more light as to what's going on.
Also, it sounds like you have a reliable reproducer. Does this reproduce
on a recent kernel?
