Subject: fix up nowarn confusion in the dma mapping layer
Date: Mon, 1 Oct 2018 13:12:55 -0700 [thread overview]
Message-ID: <20181001201257.366-1-hch@lst.de> (raw)
Hi all,
this series sorts out how we deal with the nowarn flags in the dma
mapping code. We still support __GFP_NOWARN for the legacy APIs that
don't support passing the dma specific flags, but we generally want
every implementation to actually check DMA_ATTR_NO_WARN instead.
