Subject: [PATCH 0/2] nfsd: COPY refcounting fix and cleanup
Date: Tue, 17 Jan 2023 14:38:29 -0500	[thread overview]
Message-ID: <20230117193831.75201-1-jlayton@kernel.org> (raw)

Just a couple of fixes for refcounting issues in the COPY codepaths. I
sort of doubt either of these are the cause of the more recent crash
reports around nfsd_file refcount underflows, but they do seem like real
(and potential) bugs.

Jeff Layton (2):
  nfsd: zero out pointers after putting nfsd_files on COPY setup error
  nfsd: clean up potential nfsd_file refcount leaks in COPY codepath
