mm/block: convert rw_page users to bio op use
The rw_page users were not converted to use bio/req ops. As a result bdev_write_page is not passing down REQ_OP_WRITE and the IOs will be sent down as reads. Signed-off-by: Mike Christie <mchristi@redhat.com> Fixes: 4e1b2d52a80d ("block, fs, drivers: remove REQ_OP compat defs and related code") Modified by me to: 1) Drop op_flags passing into ->rw_page(), as we don't use it. 2) Make op_is_write() and friends safe to use for !CONFIG_BLOCK Signed-off-by: Jens Axboe <axboe@fb.com>
