From: Marek Szyprowski Date: Wed, 1 Jun 2011 15:57:37 +0000 (-0300) Subject: [media] media: vb2: add __GFP_NOWARN to dma-sg allocator X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a52a82fc3a397261ecbcbd441498be58997379c8;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [media] media: vb2: add __GFP_NOWARN to dma-sg allocator Add __GFP_NOWARN parameter to videobuf2 dma-sg allocator to prevent kernel warning and stack dump if there is not enough memory available. Videobuf2 and drivers should correctly handle no memory case, so there is no need for stack dump and extensive log.
