3.6.11.3 stable review patch. If anyone has any objections, please let me know.
------------------ From: Namhyung Kim <[email protected]> [ Upstream commit 83e03b3fe4daffdebbb42151d5410d730ae50bd1 ] On the failure path, stat->start and stat->pages will refer same page. So it'll attempt to free the same page again and get kernel panic.
