Matthew Wilcox	399154be2d	dmapool: Validate parameters to dma_pool_create Check that 'align' is a power of two, like the API specifies. Align 'size' to 'align' correctly -- the current code has an off-by-one. The ALIGN macro in kernel.h doesn't. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Acked-by: David S.

Matthew Wilcox	2cae367e48	Avoid taking waitqueue lock in dmapool With one trivial change (taking the lock slightly earlier on wakeup from schedule), all uses of the waitq are under the pool lock, so we can use the locked (or __) versions of the wait queue functions, and avoid the extra spinlock.
