Noted this in my log earlier today.

Is this inotify related?

This would have been triggered by using dovecot IMAP which is configured to
use inotify on Maildir.
I'm also seeing some userspace errors logged for dovecot:

"Aug 21 04:17:22 Error: IMAP(reuben): inotify_rm_watch() failed: Invalid argument"

I'll deal with those with the guy who wrote the inotify code in dovecot.

I'm not so sure userspace should be able or need to cause the kernel to dump
stack traces like that though?
