block: blk_rq_[cur_]_{sectors|bytes}() usage cleanup
With the previous changes, the followings are now guaranteed for all requests in any valid state. * blk_rq_sectors() == blk_rq_bytes() >> 9 * blk_rq_cur_sectors() == blk_rq_cur_bytes() >> 9 Clean up accessor usages. Notable changes are * nbd,i2o_block: end_all used instead of explicit byte count * scsi_lib: unnecessary conditional on request type removed [ Impact: cleanup ] Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Paul Clements <paul.clements@steeleye.com> Cc: Pete Zaitcev <zaitcev@redhat.com> Cc: Alex Dubov <oakad@yahoo.com> Cc: Markus Lidel <Markus.Lidel@shadowconnect.com> Cc: David Woodhouse <dwmw2@infradead.org> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
