Re: [PATCH] jbd2: Remove unused exports for jbd2 debugging

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...
