Right, the lockdep call chain does not match the sources. I've rebuilt & rebooted with v3 and am not seeing any of the sysfs related messages. Tested-by: David Sterba <dste...@suse.cz> The fix is for stable 3.13+ and even better if it lands in 3.15, as it fixes a double-free that can randomly hit other subsystems due to frequent kmalloc-32 slab reuse, (eg. https://bugzilla.kernel.org/show_bug.cgi?id=72461). -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
