What is the reason for tasklet removal, I am not sure old is a reason to
remove an API...
This patch replaces the tasklet usage in drivers/dma/* with a
simple work.
Dmaengines need very high throughput, one of the reasons in dmaengine
API design to use tasklet was higher priority given to them. Will the
workqueue allow that...?
Wouldn't the logical move be to convert threaded irq IF tasklets are
being deprecated rather than using workqueue as replacement?
Also, wouldn't all the spin_lock_bh() calls need to be changed to
spin_lock_irqsave() now? Probably not as simple as just replace tasklet
with workqueue.
