jbd2: rename jbd_debug() to jbd2_debug()
The name of jbd_debug() is confusing as all functions inside jbd2 have jbd2_ prefix. Rename jbd_debug() to jbd2_debug(). No functional changes. Signed-off-by: Jan Kara <jack@suse.cz> Reviewed-by: Lukas Czerner <lczerner@redhat.com> Link: https://lore.kernel.org/r/20220608112355.4397-2-jack@suse.cz Signed-off-by: Theodore Ts'o <tytso@mit.edu>
