This is a note to let you know that I have just added a patch titled NFSv4: Fix state reference counting in to the linux-3.11.y-queue branch of the 3.11.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-3.11.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 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 968ee3aa3e2b908e10d784fe5e404812cd740509 Mon Sep 17 00:00:00 2001 From: Trond Myklebust <Trond.Myklebust@netapp.com> Date: Mon, 28 Oct 2013 14:57:12 -0400 Subject: NFSv4: Fix state reference counting in _nfs4_opendata_reclaim_to_nfs4_state commit d49f042aeec99c5f87160bb52dd52088b1051311 upstream. Currently, if the call to nfs_refresh_inode fails, then we end up leaking a reference count, due to the call to nfs4_get_open_state. While we're at it, replace nfs4_get_open_state with a simple call to atomic_inc(); there is no need to do a full lookup of the struct nfs_state since it is passed as an argument in the struct nfs4_opendata, and is already assigned to the variable 'state'.
