charset="utf-8" blk_next_bio() is the central function which allocates the bios for discard, write-same, write-zeroes and zone-mgmt. The initialization of various bio members is duplicated in disacrd, write-same, write-zeores. In this preparation patch we add bdev, sector, op, and opf arguments to the blk_next_bio() to reduce the duplication.=20 In the next patch we introduce bio_new(), this prepration patch allows us to call it inside blk_next_bio().
