Hi, Commit cebc2de44d3bce53e46476e774126c298ca2c8a9 ("dm space map metadata: fix refcount decrement below 0 which caused corruption") needs to be backported to stable 3.12+. I marked that commit header for stable 3.13+ but at that time I didn't realize commit 5b564d80 ("dm space map: disallow decrementing a reference count below zero") was tagged for 3.12+ -- so stable 3.12 is exposed without this fix, as was confirmed via this BZ: https://bugzilla.kernel.org/show_bug.cgi?id=68801 Thanks, Mike -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
