Hi,
There are two parts in this series:
"move clear_hwpoisoned_pages" and "simplify num_poisoned_pages_dec"
do not fix bugs, just make memory failure easy to maintain.

"optimize hwpoison_filter" and "add hwpoison_filter for soft offline"
try to fix hwpoison_filter.

zhenwei pi (4):
  mm/memory-failure.c: move clear_hwpoisoned_pages
  mm/memofy-failure.c:: simplify num_poisoned_pages_dec
  mm/memofy-failure.c: optimize hwpoison_filter
  mm/memofy-failure.c: add hwpoison_filter for soft offline
