From: Mike Christie <[email protected]> The bio bi_op and bi_rw is now setup, so there is no need to pass around the rq_flag_bits bits too. btrfs users should should access the bio.
v2: 1. Fix merge_bio issue where instead of removing rw/op argument I passed it in again to the merge_bio related functions.
