Subject: [PATCH v2 0/2] mm: remove the memory isolate notifier
Date: Thu, 14 Nov 2019 14:19:09 +0100	[thread overview]
Message-ID: <20191114131911.11783-1-david@redhat.com> (raw)

This is the MM part of
	https://lkml.org/lkml/2019/10/31/487

"We can get rid of the memory isolate notifier by switching to balloon
compaction in powerpc's CMM (Collaborative Memory Management). The memory
isolate notifier was only necessary to allow to offline memory blocks that
contain inflated/"loaned" pages - which also possible when the inflated
pages are movable (via balloon compaction). [...]"

Michael queued the POWERPC bits that remove the single user, but I am
missing ACKs for the MM bits. I think it makes sense to let these two
patches also go via Michael's tree, to avoid collissions. Thoughts?

v1 -> v2: (MM bits)
- "mm: remove the memory isolate notifier"
-- Remove another stale comment
-- Minor code cleanup

David Hildenbrand (2):
  mm: remove the memory isolate notifier
  mm: remove "count" parameter from has_unmovable_pages()
