From: Mike Christie <mchristi@xxxxxxxxxx>
This patch prepares mm's submit_bio use for the next
patches that split bi_rw into a operation and flags field.
Instead of passing in a bitmap with both the operation and
flags mixed in, the callers will now pass them in seperately.
This patch modifies the code related to the submit_bio calls
so the flags and operation are seperated. When this is done
for all code, one of the later patches in the series will
the actual submit_bio call, so the patches are bisectable.
