Hello, yeah, I was grepping the sources whether I can see an external use of jbd2_debug() and didn't notice the macro in include/linux/jbd2.h that is calling __jbd2_debug() is actually called jbd_debug(). I actually think we should use ext4_debug() instead of jbd_debug() in ext4 code but anyway, my patches need tweaking...
