Unify bio split code, and prepare to fix disordered split IO
Missing the period at the end of the above sentence.
Noted commit 319ff40a5427 ("md/raid0: Fix performance regression for large
sequential writes") already fix disordered split IO by converting bio to
underlying disks before submit_bio_noacct(), with the respect
md_submit_bio() already split by sectors, and raid0_make_request() will
split at most once for unaligned IO. This is a bit hacky and we'll convert
this to solution in general later.
I do not see how this is relevant to this patch. The patch is a simple
straightforward conversion of hard-coded BIO split to using
bio_submit_split_bioset(). So I would just say that.
This is just a note that why bio_split() from read/write is not
converted now, because disordered problem is fixed by above commit
already.
Later patch 15 will convert bio_split() from read/write.

With the above addressed, this looks OK to me.
