Jens tried out a similar series with some not yet sent additions: 8.2-8.3 MIOPS -> ~9 MIOPS, or 8-10%. 12/16 is bulky, but it nicely drives the numbers. Moreover, with it we can rid of some not used anymore optimisations in __blkdev_direct_IO() because it awlays serve multiple bios. E.g. no need in conditional referencing with DIO_MULTI_BIO, and _probably_ can be converted to chained bio.
