From 1011c1b9f2e45ce7c6e38888d2b83936aec38771 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 7 May 2009 22:24:45 +0900 Subject: 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 Cc: Paul Clements Cc: Pete Zaitcev Cc: Alex Dubov Cc: Markus Lidel Cc: David Woodhouse Cc: James Bottomley Cc: Boaz Harrosh Signed-off-by: Jens Axboe --- drivers/scsi/scsi_lib.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) (limited to 'drivers/scsi/scsi_lib.c') diff --git a/drivers/scsi/scsi_lib.c b/drivers/scsi/scsi_lib.c index 3d16c70fbde0..ee308f6f7982 100644 --- a/drivers/scsi/scsi_lib.c +++ b/drivers/scsi/scsi_lib.c @@ -546,7 +546,7 @@ static struct scsi_cmnd *scsi_end_request(struct scsi_cmnd *cmd, int error, * to queue the remainder of them. */ if (blk_end_request(req, error, bytes)) { - int leftover = blk_rq_sectors(req) << 9; + int leftover = blk_rq_bytes(req); if (blk_pc_request(req)) leftover = req->resid_len; @@ -964,10 +964,7 @@ static int scsi_init_sgtable(struct request *req, struct scsi_data_buffer *sdb, count = blk_rq_map_sg(req->q, req, sdb->table.sgl); BUG_ON(count > sdb->table.nents); sdb->table.nents = count; - if (blk_pc_request(req)) - sdb->length = blk_rq_bytes(req); - else - sdb->length = blk_rq_sectors(req) << 9; + sdb->length = blk_rq_bytes(req); return BLKPREP_OK; } -- cgit v1.2.3
