Subject: [PATCH 0/8] nfsd: fixes for locally-triggerable bugs
Date: Mon, 01 Jun 2026 13:31:03 -0400 [thread overview]
Message-ID: <20260601-nfsd-testing-v1-0-d0f61e536df8@kernel.org> (raw)
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.
