      blk-mq: return when hctx is stopped in blk_mq_run_work_fn · 0196d6b4
      Jianchao Wang authored
      If a hardware queue is stopped, it should not be run again before
      explicitly started. Ignore stopped queues in blk_mq_run_work_fn(),
      fixing a regression recently introduced when the START_ON_RUN bit
      was removed.
      
      Fixes: 15fe8a90 ("blk-mq: remove blk_mq_delay_queue()")

      Revert "fs: fold open_check_o_direct into do_dentry_open" · af04fadc
      Al Viro authored
      This reverts commit cab64df1.
      
      Having vfs_open() in some cases drop the reference to
      struct file combined with
      
      	error = vfs_open(path, f, cred);
      	if (error) {
      		put_filp(f);
      		return ERR_PTR(error);
      	}
      	return f;
      
      is flat-out wrong.  It used to be
      
      		error = vfs_open(path, f, cred);
      		if (!error) {
      			/* from now on we need fput() to dispose of f */
      			error = open_check_o_direct(f);
      			if (error) {
      				fput(f);
      				f = ERR_PTR(error);
      			}
      		} else {
      			put_filp(f);
      			f = ERR_PTR(error);
      		}
      
      and sure, having that open_check_o_direct() boilerplate gotten rid of is
      nice, but not that way...
      
      Worse, another call chain (via finish_open()) is FUBAR now wrt
      FILE_OPENED handling - in that case we get error returned, with file
      already hit by fput() *AND* FILE_OPENED not set.  Guess what happens in
      path_openat(), when it hits
      
      	if (!(opened & FILE_OPENED)) {
      		BUG_ON(!error);
      		put_filp(file);
      	}
      
      The root cause of all that crap is that the callers of do_dentry_open()
      have no way to tell which way did it fail; while that could be fixed up
      (by passing something like int *opened to do_dentry_open() and have it
      marked if we'd called ->open()), it's probably much too late in the
      cycle to do so right now.

      blk-mq: update nr_requests when switching to 'none' scheduler · 32a50fab
      Ming Lei authored
      Now we setup q->nr_requests when switching to one new scheduler,
      but not do it for 'none', then q->nr_requests may not be correct
      for 'none'.
      
      This patch fixes this issue by always updating 'nr_requests' when
      switching to 'none'.

      block: don't use blocking queue entered for recursive bio submits · cd4a4ae4
      Jens Axboe authored
      If we end up splitting a bio and the queue goes away between
      the initial submission and the later split submission, then we
      can block forever in blk_queue_enter() waiting for the reference
      to drop to zero. This will never happen, since we already hold
      a reference.
      
      Mark a split bio as already having entered the queue, so we can
      just use the live non-blocking queue enter variant.
      
      Thanks to Tetsuo Handa for the analysis.
