If a NFS client receives a delegation for a file after it has taken a lock on that file, we can currently end up in a situation where we mistakenly skip unlocking that file. The following patch swaps an erroneous check in nfs4_proc_unlck for whether or not the file has a delegation to one which checks whether or not we hold a lock stateid for that file. Reported-by:
