This is a note to let you know that I have just added a patch titled dm thin: fix dangling bio in process_deferred_bios error path 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 018f5fe5d2bc1213196c161af3e8ed772cdc6120 Mon Sep 17 00:00:00 2001 From: Mike Snitzer <snitzer@redhat.com> Date: Fri, 28 Mar 2014 02:15:02 -0400 Subject: dm thin: fix dangling bio in process_deferred_bios error path commit fe76cd88e654124d1431bb662a0fc6e99ca811a5 upstream. If unable to ensure_next_mapping() we must add the current bio, which was removed from the @bios list via bio_list_pop, back to the deferred_bios list before all the remaining @bios.
