Re: [PATCH] block: consider merge of segments when merge bio into rq

So the check change here looks good to me.

I don't like like the duplicate code, can you look into sharing
the new segment checks between the two functions and the existing
instance in ll_merge_requests_fn by passing say two struct bio *bio1
and struct bio *bio2 pointer instead of using req->bio and req->biotail?

Also please include the information that you posted in the reply to
the other patch in the description for this one.
