From 0c7c3e67ab91ec6caa44bdf1fc89a48012ceb0c5 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 28 Mar 2013 20:37:14 -0400 Subject: [PATCH] nfsd4: don't close read-write opens too soon MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 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.
