Still not sure why I don't see the leaks after repeated > mkfs.xfs runs, though. You can force more kmemleak scans via: echo scan > /sys/kernel/debug/kmemleak In my case, the leaks were reported for ext4 and appeared during boot, no need for mkfs. But kmemleak favours false negatives more than positives (otherwise it would be pretty unusable), so you don't always hit them. -- Catalin -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
