2009-09-11	block: use interrupts disabled version of raise_softirq_irqoff()	Jens Axboe	1	-1/+1
	We already have interrupts disabled at that point, so use the __raise_softirq_irqoff() variant. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2009-09-11	block: adjust default budget for blk-iopoll	Jens Axboe	1	-1/+3
	It's not exported, I doubt we'll have a reason to change this... Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-09-11	block: fix long lines in block/blk-iopoll.c	Jens Axboe	1	-12/+14
	Note sure why they happened in the first place, probably some bad terminal setting. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-09-11	block: add blk-iopoll, a NAPI like approach for block devices	Jens Axboe	1	-0/+220
	This borrows some code from NAPI and implements a polled completion mode for block devices. The idea is the same as NAPI - instead of doing the command completion when the irq occurs, schedule a dedicated softirq in the hopes that we will complete more IO when the iopoll handler is invoked. Devices have a budget of commands assigned, and will stay in polled mode as long as they continue to consume their budget from the iopoll softirq handler. If they do not, the device is set back to interrupt completion mode. This patch holds the core bits for blk-iopoll, device driver support sold separately.
