v5.14 is almost 2 years old.  Why are you testing such an old kernel version?
This bug could have already been fixed almost 2 years ago.

Also, if you think this is a bug in eventpoll, this report should be sent to
linux-fsdevel, as per './scripts/get_maintainer.pl fs/eventpoll.c'.  It's
unclear why you are sending this report to linux-scsi.

I think you answered your own question.  It doesn't have a reproducer;
therefore, it's not reproducible.
