Re: [patch] fix the 2nd buffer race properly

The bug (the reason I asked you to drop the patch just now)
was that the code previously did a get_bh on all bh's in a
page, but I changed it to only put_bh the ones to be written.

The minor fix for that was to only get_bh the buffer heads to
be written.

Err, that wasn't very clear: my earlier patch to fix the problem
introduced the above bh leak, but was otherwise correct in that
it solved the underlying problem.
