 ok, then i think i understand the problem.
 we should throttle activities creating dirty buffers.
 maybe by having a flag for getblk and friends to tell
 "we are not going to dirty the buffer".
 
 what your patch does is the opposite.  ie. throttling attempts of
 cleaning buffers.  i believe it makes the situation worse.
