Actually, that fix 42691398be08 ("nfsd: Fix race between FREE_STATEID and LOCK") from v4.8-rc2 reported by Alexey Kodanev (LTP network maintainer) was found by nfslock01 test [1], which is integrated into other LTP NFS tests [2]. I'd definitely keep these in LTP. nfsv4 I proposed to remove as outdated and not being used are testing ACL [3] and fcntl locking [4]. ACL tests use rsh and aren't integrated into LTP framework (use their custom [5] runtest file thus I doubt anyone is using it). fcntl locktests are at least integrated into LTP (use fcntl-locktests runtest file[6], I forget to remove it in this patch). Both tests are written in 2005. I don't want to push for removal, if you see any use in it.
