Date: Thu, 21 Jun 2007 09:34:55 -0700 From: Shannon Nelson <shannon.nelson@...el.com> To: Dave Miller <davem@...emloft.net> Cc: netdev@...r.kernel.org Subject: [PATCH] NET: [CORE] Re-enable irqs before pushing pending DMA requests This moves the local_irq_enable() call in net_rx_action() to before calling the CONFIG_NET_DMA's dma_async_memcpy_issue_pending() rather than after. This shortens the irq disabled window and allows for DMA drivers that need to do their own irq hold.
