This is a note to let you know that I have just added a patch titled SUNRPC: Set alloc_slot for backchannel tcp ops 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. -Herton ------ From fe3c8471dd5d774005c89a2573567cee4089a5ed Mon Sep 17 00:00:00 2001 From: Bryan Schumaker <bjschuma@netapp.com> Date: Mon, 24 Sep 2012 13:39:01 -0400 Subject: [PATCH 11/11] SUNRPC: Set alloc_slot for backchannel tcp ops commit 84e28a307e376f271505af65a7b7e212dd6f61f4 upstream. f39c1bfb5a03e2d255451bff05be0d7255298fa4 (SUNRPC: Fix a UDP transport regression) introduced the "alloc_slot" function for xprt operations, but never created one for the backchannel operations. This patch fixes a null pointer dereference when mounting NFS over v4.1.
