Hi,
Since this commit:
commit c3f207ab29f793b8c942ce8067ed123f18d5b81b
Author: Rohith Surabattula <rohiths@microsoft.com>
Date: Tue Apr 13 00:26:42 2021 -0500
cifs: Deferred close for files
Xfstests generic/478 on CIFS can't finish like before. The test programme
never returns but killable. The kernel does not warn about soft or hard
lockups. So it looks like looping forever at some point.
It's always reproducible. Without this commit, generic/478 fails the test
because of different lock schema but complete very fast. With this commit,
test hang like forever.
Sorry that I do not look further here, because I have another bisecting to
do to hunting another regression.
Thanks,
Murphy

Can you please share the mount options.
Did you observe the same failure with 5.14-rc5-smb3-fixes ?
I ran the generic/478 test on 5.14 and didn't see any hang. But, test
fails with below
generic/478 - output mismatch (see
