It's still untested, but I realized that the whole
"blk_flush_plug_list(plug, true);" thing is pointless, since
schedule() itself will do that for us.

So I think you can remove the

+ struct blk_plug *plug = current->plug;
+ if (plug)
+ blk_flush_plug_list(plug, true);

part from congestion_timeout().

Not that it should *hurt* to have it there, so I'm not bothering to
send a changed patch.

And again, no actual testing by me on any of this, just looking at the code.
