Subject: [GIT PULL] nfsd changes for 5.17
Hi Linux-
Happy new year! First, the news:
Bruce has announced he is leaving Red Hat at the end of the month
and is stepping back from his role as NFSD co-maintainer. This pull
request includes a patch removing him from the MAINTAINERS file.
There is one patch in this PR that Jeff Layton was carrying in the
locks tree. Since he had only one for this cycle, he asked us to
send it to you via the nfsd tree.
There continues to be 0-day reports from Robert Morris @MIT. This
time we include a fix for a crash in the COPY_NOTIFY operation.
Pull request details:
A while back, Stephen Rothwell reported a minor merge conflict with
the userns tree:
https://lore.kernel.org/linux-next/20211217181325.4fa394c4@canb.auug.org.au/T/#u
I'm not sure exactly how this conflict is resolved with recent
linux-next trees, but the original resolution was small and correct
and no problems have been reported since then.
The following changes since commit 2585cf9dfaaddf00b069673f27bb3f8530e2039c:
Linux 5.16-rc5 (2021-12-12 14:53:01 -0800)
