Subject: please revert [PATCH bpf-next v5 03/15] xsk: create and free buffer pool independently from umem
Date: Mon, 5 Oct 2020 09:35:35 +0100 [thread overview]
Message-ID: <20201005083535.GA512@infradead.org> (raw)
In-Reply-To: <1598603189-32145-4-git-send-email-magnus.karlsson@intel.com>
Hi Dave,
please can you rever this? This is the second xsk patch this year
that pokes into dma-mapping internals for absolutely not reason.
And we discussed this in detail the last time around: drivers have
absolutely no business poking into dma-direct.h and dma-noncoherent.h.
In fact because people do this crap I have a patch to remove these
headers that I'm about to queue up, so if this doesn't get reverted
the linux-next build will break soon.
