   1 jbd2: simplify error path on allocation failure in do_get_write_access()
   2
   3 From: Jan Kara <jack@suse.cz>
   4
   5 We were acquiring bh_state_lock when allocation of buffer failed in
   6 do_get_write_access() only to be able to jump to a label that releases
   7 the lock and does all other checks that don't make sense for this error
   8 path. Just jump into the right label instead.
