From bc2da6406bec3dfffde77426330468e40243b1ea Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 28 Mar 2013 20:37:14 -0400 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 commit 0c7c3e67ab91ec6caa44bdf1fc89a48012ceb0c5 upstream. 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.
