This is part of a series that I'm working on and that aims to remove the bdrv_aio_*() emulation in io.c. blkdebug and blkverify were easy, but for quorum I need a few more patches, so I'm sending this out as an RFC while I continue work on the rest (QED, and then possibly some polishing).
After the series, quorum doesn't only use the preferred interfaces, but the code becomes a little easier to follow and byte granularity requests are supported. There is probably still some potential for additional cleanups in a follow-up series, but this should already be enough to be worth merging.
