Subject: [PATCH AUTOSEL 5.10 30/34] scsi: sr: Don't use GFP_DMA
Date: Mon, 17 Jan 2022 12:03:20 -0500	[thread overview]
Message-ID: <20220117170326.1471712-30-sashal@kernel.org> (raw)
In-Reply-To: <20220117170326.1471712-1-sashal@kernel.org>

From: Christoph Hellwig <hch@lst.de>

[ Upstream commit d94d94969a4ba07a43d62429c60372320519c391 ]

The allocated buffers are used as a command payload, for which the block
layer and/or DMA API do the proper bounce buffering if needed.
