Subject: [PATCH 01/19] iwlwifi: stop passing bogus gfp flags arguments to dma_alloc_coherent
Date: Sat, 31 Aug 2019 12:48:41 +0300	[thread overview]
Message-ID: <20190831094859.6391-2-luca@coelho.fi> (raw)
In-Reply-To: <20190831094859.6391-1-luca@coelho.fi>

From: Christoph Hellwig <hch@lst.de>

dma_alloc_coherent is not just the page allocator.  The only valid
arguments to pass are either GFP_ATOMIC or GFP_ATOMIC with possible
modifiers of __GFP_NORETRY or __GFP_NOWARN.
