Date: Thu, 24 Apr 2014 09:50:27 +0100 From: Luis Henriques <luis.henriques@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Mike Snitzer <snitzer@...hat.com>, Luis Henriques <luis.henriques@...onical.com> Subject: [PATCH 3.11 102/182] dm thin: fix dangling bio in process_deferred_bios error path 3.11.10.9 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Mike Snitzer <snitzer@...hat.com> 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.
