Hi,
This patchset tries to solve the issue among memory_hotplug, hugetlb and hwpoison.
In this patchset, memory hotplug handles hwpoison pages like below:
- hwpoison pages should not prevent memory hotremove,
- memory block with hwpoison pages should not be onlined.
Changes in this version:
- (patch 1/4) determine migratable_cleared atomically by introducing
TESTCLEARHPAGEFLAG (suggested by Miaohe),
- (patch 4/4) cleaned up declarations of counter API,
- rebased onto akpm/mm-unstable on Oct 23.
Thanks,
Naoya Horiguchi
