Subject: nfsd4: don't close read-write opens too soon
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Don't actually close any opens until we don't need them at all.
This means being left with write access when it's not really necessary,
but that's better than putting a file that might still have posix locks
held on it, as we have been.
