jbd2: save some atomic ops in __JI_COMMIT_RUNNING handling
Currently we used atomic bit operations to manipulate __JI_COMMIT_RUNNING bit. However this is unnecessary as i_flags are always written and read under j_list_lock. So just change the operations to standard bit operations. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
