The ext4 portion has been added to the ext4 patch queue. Jan, you want to add this to the ext3 tree? - Ted jbd: /sys/kernel/debug/jbd/jbd-debug should be writable. From: "Yin, Kangkai" <kangkai.yin@...el.com> Make this sysfs file writeable so we can enable debugging without needing to reboot and futzing with boot command-line option.
