Subject[Patch v4 0/8] bugfix for memory hotplug
Date
The last version is here:
https://lkml.org/lkml/2012/10/19/56

Note: patch 1-3 are in -mm tree and I don't touch them. The other patches
except patch6 are also in mm tree. Patch 6 is not touched.

Changes from v3 to v4:
Patch4: use dynamically allocated memory instead of static array.
Patch5: merge [patchv3 2-3] into a single patch, and update it as we use
dynamically allocated memory
Patch7: merge [patchv3 5-6] into a single patch
Patch8: merge [patchv3 9] and its fix into a patch

Changes from v2 to v3:
Merge the bug fix from ishimatsu to this patchset(Patch 1-3)
Patch 3: split it from patch as it fixes another bug.
Patch 4: new patch, and fix bad-page state when hotadding a memory
device after hotremoving it. I forgot to post this patch in v2.
Patch 6: update it according to Dave Hansen's comment.

Changes from v1 to v2:
Patch 1: updated according to kosaki's suggestion

Patch 2: new patch, and update mce_bad_pages when removing memory.

Patch 4: new patch, and fix a NR_FREE_PAGES mismatch, and this bug
cause oom in my test.

Patch 5: new patch, and fix a new bug. When repeating to online/offline
pages, the free pages will continue to decrease.

Wen Congyang (6):
memory-hotplug: auto offline page_cgroup when onlining memory block
failed
memory-hotplug: fix NR_FREE_PAGES mismatch
numa: convert static memory to dynamically allocated memory for per
node device
clear the memory to store struct page
memory-hotplug: current hwpoison doesn't support memory offline
memory-hotplug: allocate zone's pcp before onlining pages

Yasuaki Ishimatsu (2):
memory hotplug: suppress "Device memoryX does not have a release()
function" warning
suppress "Device nodeX does not have a release() function" warning
