Bart Van Assche 2ee177e945 irq_poll: Fix irq_poll_sched()
The IRQ_POLL_F_SCHED bit is set as long as polling is ongoing.
This means that irq_poll_sched() must proceed if this bit has
not yet been set.

Fixes: commit ea51190c03 ("irq_poll: fold irq_poll_sched_prep into irq_poll_sched").

Christoph Hellwig ea51190c03 irq_poll: fold irq_poll_sched_prep into irq_poll_sched
There is no good reason to keep them apart, and this makes using the API
a bit simpler.

Christoph Hellwig 78d0264eb7 irq_poll: don't disable new irq_poll instances
There is no good reason to start out disabled - drivers can control if
the poll instance can be scheduled by simply not scheduling it yet.

Christoph Hellwig 511cbce2ff irq_poll: make blk-iopoll available outside the block layer
The new name is irq_poll as iopoll is already taken.  Better suggestions
welcome.
