I've told you this before -- sleeping in make_request is not illegal,
heck it happens _all the time_. Safely sleeping requires a reserved pool
of the units you wish to allocate, of course. In fact I think that would
be much nicer than the path you are following here by delaying
allocations to the loop thread (and still not using a reserved pool).

Briefly looking through the patch.

- loop_put_buffer(), it looks racy to check waitqueue_active there.

- if(!bh) return((struct buffer_head *)0);
eww!

- Also, please adher to the style. VaRiAbLe names can hurt the eyes, and
stuff like

if (something) break;
return(val);

etc don't belong too. Could you fix that up?

That said, thanks for fixing it!
