Subject: dev_pagemap related cleanups v4
Date: Mon, 1 Jul 2019 08:19:58 +0200 [thread overview]
Message-ID: <20190701062020.19239-1-hch@lst.de> (raw)
Hi Dan, Jérôme and Jason,
below is a series that cleans up the dev_pagemap interface so that
it is more easily usable, which removes the need to wrap it in hmm
and thus allowing to kill a lot of code
Note: this series is on top of Linux 5.2-rc6 and has some minor
conflicts with the hmm tree that are easy to resolve.

Gitweb:
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/hmm-devmem-cleanup.4
Changes since v3:
- pull in "mm/swap: Fix release_pages() when releasing devmap pages" and
rebase the other patches on top of that
- fold the hmm_devmem_add_resource into the DEVICE_PUBLIC memory removal
patch
- remove _vm_normal_page as it isn't needed without DEVICE_PUBLIC memory
- pick up various ACKs
Changes since v2:
- fix nvdimm kunit build
- add a new memory type for device dax
- fix a few issues in intermediate patches that didn't show up in the end
result
- incorporate feedback from Michal Hocko, including killing of
the DEVICE_PUBLIC memory type entirely
Changes since v1:
- rebase
- also switch p2pdma to the internal refcount
- add type checking for pgmap->type
- rename the migrate method to migrate_to_ram
- cleanup the altmap_valid flag
- various tidbits from the reviews
