To avoid confusion between REQ_OP_FLUSH, which is handled by
request_fn drivers, and upper layers requesting the block layer
perform a flush sequence along with possibly a WRITE, this patch
renames REQ_FLUSH to REQ_PREFLUSH.

The following patches begin to cleanup the request->cmd_flags and
bio->bi_rw mess. We currently use cmd_flags to specify the operation,
attributes and state of the request. For bi_rw we use it for similar
info and also the priority but then also have another bi_flags field
for state. At some point,

The following patches separate the operation (write, read, discard,

request/bio operations, adds fields to the request/bio to set them, and
some temporary compat code so the kernel/modules can use either one. In

This has callers of submit_bio/submit_bio_wait set the bio->bi_rw

This patch has btrfs's submit_one_bio callers set the bio->bi_op to a
REQ_OP and the bi_rw to rq_flag_bits.
The next patches will continue to convert btrfs,
so submit_bio_hook and merge_bio_hook
related code will be modified to take only the bio. I did
not do it in this patch

This patch has the dio code set the bio bi_op to a REQ_OP and bio op_flags
to rq_flag_bits.
It also begins to convert btrfs's dio_submit_t because of the dio submit_io
callout use. In the btrfs_submit_direct change, I OR'd the op and flag back
together. It is only temporary.

This patch converts the simple bi_rw use cases in the block,
drivers, mm and fs code to set the bio->bi_op to a REQ_OP.
These should be simple one liner cases, so I just did them
in one patch. The next patches handle the more complicated
cases in a module per patch.

The bio bi_op and bi_rw is now setup, so there is no need
to pass around the rq_flag_bits bits too. btrfs users should should

I passed it in again to the merge_bio related functions.
