This is a note to let you know that I have just added a patch titled nfsd4: fix nfs4 stateid leak to the linux-3.5.y-queue branch of the 3.5.yuz 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.yuz tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ From 44ae26e4035d3119acfc135e9ed68e8eaf1abb4f Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" <bfields@redhat.com> Date: Wed, 29 Aug 2012 15:21:58 -0700 Subject: [PATCH] nfsd4: fix nfs4 stateid leak commit cf9182e90b2af04245ac4fae497fe73fc71285b4 upstream. Processes that open and close multiple files may end up setting this oo_last_closed_stid without freeing what was previously pointed to. This can result in a major leak, visible for example by watching the nfsd4_stateids line of /proc/slabinfo.
