* dmapool: Validate parameters to dma_pool_createMatthew Wilcox2007-12-041-7/+8
| | | | | | | | | 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. Miller <davem@davemloft.net>
* Avoid taking waitqueue lock in dmapoolMatthew Wilcox2007-12-041-4/+5
| | | | | | | | | | 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.
