From: Mike Christie <mchri...@redhat.com>
The next patches will prepare the submit_bio users
for the split. There were a lot more users than
there were for submit_bio_wait, so if the conversion
was not a one liner, I broke it out into its own
patch.
This patch prepares blkdev_issue_discard.
There is some compat code left which will be dropped
in later patches in the series.
1. REQ_WRITE is still being set. This is because a lot
of code assumes it will be set for discard, flushes and
write sames.
2. submit_bio is still taking a bitmap. This is to make
the series git bisectable.
