I found this report from last year that seems to match a problem encountered on one of our non-opensuse servers. I dropped by irc://libera.chat/opensuse to see if I could find the bug and patch to check the source of our CIFS module to see if it was missing.
They told me to ask the kernel list.
Can you help? Thanks.
Just to follow up on this. https://github.com/openSUSE/kernel/commit/a52930353eaf443489a350a135c5525a4a...
Apparently wasn't flagged as fixes/cc:stable making it easy to overlook in other fixed release distros.
Anyway. All cleared up.
