And how quickly have you usually seen the problems? Would you have
considered two ours "good" in your bisection thing?

Also, just to check: Hugh sent out a patch called "mm: fix warning in
__set_page_dirty_nobuffers". Is that applied in your tree too, or did
the __set_page_dirty_nobuffers() warning go away with just the revert?

I'm just trying to figure out exactly what you are testing. When you
said "test with that (and Hugh's last patch) backed out", the "and
Hugh's last patch" part was a bit ambiguous. Do you mean the trial
patch in this thread (backed out) or do you mean "*with* Hugh's patch
for the __set_page_dirty_nobuffers() warning".
