From: Eric Biggers <ebiggers@xxxxxxxxxx> From: Jan Kara <jack@xxxxxxx> commit 4978c659e7b5c1926cdb4b556e4ca1fd2de8ad42 upstream. We use jbd_debug() in some places in ext4. It seems a bit strange to use jbd2 debugging output function for ext4 code. Also these days ext4_debug() uses dynamic printk so each debug message can be enabled / disabled on its own so the time when it made some sense to have these combined (to allow easier common selecting of messages to report) has passed. Just convert all jbd_debug() uses in ext4 to ext4_debug().
