This commit adds fixed tracepoint for jbd. It has been based on fixed tracepoints for jbd2, however there are missing those for collecting statistics, since I think that it will require more intrusive patch so I should have its own commit, if someone decide that it is needed. Also there are new tracepoints in __journal_drop_transaction() and journal_update_superblock(). The list of jbd tracepoints: jbd_checkpoint jbd_start_commit jbd_commit_locking jbd_commit_flushing jbd_commit_logging jbd_drop_transaction jbd_end_commit jbd_do_submit_data jbd_cleanup_journal_tail jbd_update_superblock_end Signed-off-by: Lukas Czerner <lczerner@redhat.com> Cc: Jan Kara <jack@suse.cz> Signed-off-by: Jan Kara <jack@suse.cz>
