Trond Myklebust 0df5dd4aae NFSv4: fix delegated locking ... Arnaud Giersch reports that NFSv4 locking is broken when we hold a delegation since commit 8e469ebd6d (NFSv4: Don't allow posix locking against servers that don't support it). According to Arnaud, the lock succeeds the first time he opens the file (since we cannot do a delegated open) but then fails after we start using delegated opens. The following patch fixes it by ensuring that locking behaviour is governed by a per-filesystem capability flag that is initially set, but gets cleared if the server ever returns an OPEN without the NFS4_OPEN_RESULT_LOCKTYPE_POSIX flag being set.
