Date: Mon, 29 Feb 2016 16:22:32 +0100 From: Lars Persson <lars.persson@...s.com> To: netdev@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Rabin Vincent <rabinv@...s.com>, Lars Persson <larper@...s.com> Subject: [PATCH net 3/5] dwc_eth_qos: use GFP_KERNEL in dma_alloc_coherent() From: Rabin Vincent <rabinv@...s.com> Since we are in non-atomic context here we can pass GFP_KERNEL to dma_alloc_coherent(). This enables use of the CMA.
