[PATCH] nfsd4: rename lk_stateowner
One of the things that's confusing about nfsd4_lock is that the lk_stateowner field could be set to either of two different lockowners: the open owner or the lock owner. Rename to lk_replay_owner and add a comment to make it clear that it's used for whichever stateowner has its sequence id bumped for replay detection. Signed-off-by: J.
