OK.
Longer-term it would be best to lose the PF_SYNCWRITE thing and to just
mark the BIOs as synchronous prior to submitting them. It's a matter of
transferring the info in writeback_control.sync_mode at the pagecache/BIO
boundary: mpage_bio_submit(), __block_write_full_page->submit_bh(), etc.
But we can worry about that later, once it is established that the
synchronous write detection is sufficiently useful.
