Subject: dma-direct cleanups
Date: Tue, 19 Oct 2021 14:29:12 +0200 [thread overview]
Message-ID: <20211019122916.2468032-1-hch@lst.de> (raw)
Hi all,
Linus complained about the complex flow in dma_direct_alloc, so this
tries to simplify it a bit, and while I was at it I also made sure that
unencrypted pages never leak back into the page allocator.
