Jens Axboe 4aff5e2333 [PATCH] Split struct request ->flags into two parts
Right now ->flags is a bit of a mess: some are request types, and
others are just modifiers. Clean this up by splitting it into
->cmd_type and ->cmd_flags. This allows introduction of generic
Linux block message types, useful for sending generic Linux commands
to block devices.

Jens Axboe 1959d21232 [PATCH] Only the first two bits in bio->bi_rw and rq->flags match
Not three, as assumed. This causes the barrier bit to be needlessly set
for some IO.
