SubjectRe: lowlatency-2.2.14-B1 + 2.2.14aa7 fixes crash, but...

unless browsing the whole list takes more than the task timeslice (around
10msec with a reniced +20 task). With 2giga in buffer cache 10msec of
latnecy are realistic. If that will happen what you suggested above will
cause the task to hang forever in R state.

Also after the b_count-- you can process the bh. You should "goto repeat"
only after processing the bh. Just like what I am doing in 2.3.47 in
invalidate_buffers/set_blocksize.
