Subject: [PATCH v2 0/3] mm/gup: introduce vaddr_pin_pages_remote(), FOLL_PIN
Date: Tue, 20 Aug 2019 21:07:24 -0700	[thread overview]
Message-ID: <20190821040727.19650-1-jhubbard@nvidia.com> (raw)

Hi Ira,

This is for your tree. I'm dropping the RFC because this aspect is
starting to firm up pretty well.

I've moved FOLL_PIN inside the vaddr_pin_*() routines, and moved
FOLL_LONGTERM outside, based on our recent discussions. This is
documented pretty well within the patches.

Note that there are a lot of references in comments and commit
logs, to vaddr_pin_pages(). We'll want to catch all of those if
we rename that. I am pushing pretty hard to rename it to
vaddr_pin_user_pages().

v1 of this may be found here:
