[PATCH 0/8] nfsd: fixes for locally-triggerable bugs
Posted by Jeff Layton 6 days, 10 hours ago
These are bugs that Claude classified as locally-triggerable. A couple
can be triggered by an unprivileged user, but the rest require admin
access.

The last 3 patches fix one bug. I originally had a more targeted fix
that kres generated, but I think it's better to simplify the filecache
disposal mechanism to get rid of the bug rather than add more
complexity.
