Subject: [PATCH 0/2] pci sysfs file iomem revoke support
Date: Thu,  4 Feb 2021 17:58:29 +0100	[thread overview]
Message-ID: <20210204165831.2703772-1-daniel.vetter@ffwll.ch> (raw)

Hi all,

This is a revised version of patch 12 from my series to lock down some
follow_pfn vs VM_SPECIAL races:

https://lore.kernel.org/dri-devel/CAKwvOdnSrsnTgPEuQJyaOTSkTP2dR9208Y66HQG_h1e2LKfqtw@mail.gmail.com/

Stephen reported an issue on HAVE_PCI_LEGACY platforms which this patch
set tries to address. Previous patches are all still in linux-next.

Stephen, would be awesome if you can give this a spin.

Björn/Greg, review on the first patch is needed, I think that's the
cleanest approach from all the options I discussed with Greg in this
thread:

https://lore.kernel.org/dri-devel/CAKMK7uGrdDrbtj0OyzqQc0CGrQwc2F3tFJU9vLfm2jjufAZ5YQ@mail.gmail.com/

Cheers, Daniel
