This series replaces nfsd: drop st_mutex and rp_mutex before calling move_to_close_lru() which was recently dropped as a problem was found. The first two patches rearrange code without important functional change. The last two address the two relaced problems of two different mutexes which are held while waiting and can each trigger a deadlock. This is against v6.9-rc2. Thanks, NeilBrown [PATCH 1/4] nfsd: perform all find_openstateowner_str calls in the [PATCH 2/4] nfsd: move nfsd4_cstate_assign_replay() earlier in open [PATCH 3/4] nfsd: replace rp_mutex to avoid deadlock in [PATCH 4/4] nfsd: drop st_mutex before calling move_to_close_lru()
