This is a note to let you know that I have just added a patch titled nfsd4: don't close read-write opens too soon to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 9098b3534e053fc61a413ae0997aa8d09e1c2d6d Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" <bfields@redhat.com> 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=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.
