[PATCH] direct-to-BIO writeback
Multipage BIO writeout from the pagecache.
It's pretty much the same as multipage reads. It falls back to buffers
if things got complex.
The write case is a little more complex because it handles pages which
have buffers and pages which do not. If the page didn't have buffers
this code does not add them.
