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
When account the nr_phys_segments during merging bios into rq,
only consider segments merging in individual bio but not all
the bios in a rq. This leads to the bigger nr_phys_segments of
rq than the real one when the segments of bios in rq are
contiguous and mergeable. The nr_phys_segments of rq
