Subject: [PATCH 0/4] SGL alloc and free helper functions for requests
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Hey,

These patches are going to be part of the P2PDMA patchset I'm working
on. The change was suggested by Christoph. I just wanted to get the NVMe
community's initial feedback on them seperate from our main patchset.

That is, except for patch 0003 which I'm pretty sure is a valid bug fix
but it needs review.

I also can not test the fibre channel changes as I do not have hardware
so I'd also appreciate it if someone can test it out.

If you need more context the commit which modifies these to support
P2P is [1]. This will likely be posted as the next version of the P2PDMA
patchset in the next cycle.

Thanks,

Logan
