From 296b2f6ae654581adc27f0d6f0af454c7f3d06ee Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 8 May 2009 11:54:15 +0900 Subject: block: convert to dequeueing model (easy ones) plat-omap/mailbox, floppy, viocd, mspro_block, i2o_block and mmc/card/queue are already pretty close to dequeueing model and can be converted with simple changes. Convert them. While at it, * xen-blkfront: !fs check moved downwards to share dequeue call with normal path. * mspro_block: __blk_end_request(..., blk_rq_cur_byte()) converted to __blk_end_request_cur() * mmc/card/queue: loop of __blk_end_request() converted to __blk_end_request_all() [ Impact: dequeue in-flight request ] Signed-off-by: Tejun Heo Cc: Rusty Russell Cc: Jeremy Fitzhardinge Cc: Stephen Rothwell Cc: Alex Dubov Cc: Markus Lidel Cc: Pierre Ossman Signed-off-by: Jens Axboe --- drivers/memstick/core/mspro_block.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'drivers/memstick') diff --git a/drivers/memstick/core/mspro_block.c b/drivers/memstick/core/mspro_block.c index 93b2c6185656..58f5be8cd69e 100644 --- a/drivers/memstick/core/mspro_block.c +++ b/drivers/memstick/core/mspro_block.c @@ -672,8 +672,7 @@ try_again: msb->req_sg); if (!msb->seg_count) { - chunk = __blk_end_request(msb->block_req, -ENOMEM, - blk_rq_cur_bytes(msb->block_req)); + chunk = __blk_end_request_cur(msb->block_req, -ENOMEM); continue; } @@ -711,6 +710,7 @@ try_again: dev_dbg(&card->dev, "issue end\n"); return -EAGAIN; } + blkdev_dequeue_request(msb->block_req); dev_dbg(&card->dev, "trying again\n"); chunk = 1; @@ -825,8 +825,10 @@ static void mspro_block_submit_req(struct request_queue *q) return; if (msb->eject) { - while ((req = elv_next_request(q)) != NULL) + while ((req = elv_next_request(q)) != NULL) { + blkdev_dequeue_request(req); __blk_end_request_all(req, -ENODEV); + } return; } -- cgit v1.2.3
