[BLOCK] bio: check for same page merge possibilities in __bio_add_page()
For filesystems with a blocksize < page size, we can merge same page calls into the bio_vec at the end of the bio. This saves segments on systems with a page size > the "normal" 4kb fs block size. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@suse.de>
