Subject: [PATCH v2 0/2] mm: Memory offlining + page isolation cleanups
Date: Mon, 21 Oct 2019 19:23:51 +0200	[thread overview]
Message-ID: <20191021172353.3056-1-david@redhat.com> (raw)

Two cleanups that popped up while working on (and discussing) virtio-mem:
 https://lkml.org/lkml/2019/9/19/463

Tested with DIMMs on x86.

As discussed with michal in v1, I'll soon look into removing the use
of PG_reserved during memory onlining completely - most probably
disallowing to offline memory blocks with holes, cleaning up the
onlining+offlining code.

v1 -> v2:
- "mm/page_alloc.c: Don't set pages PageReserved() when offlining"
-- Fixup one comment
- "mm/page_isolation.c: Convert SKIP_HWPOISON to MEMORY_OFFLINE"
-- Use parenthesis around checks
- Added ACKs

David Hildenbrand (2):
  mm/page_alloc.c: Don't set pages PageReserved() when offlining
  mm/page_isolation.c: Convert SKIP_HWPOISON to MEMORY_OFFLINE
