memory_failure and soft_offline_path paths now drain pcplists by calling get_hwpoison_page. memory_failure flags the page as HWPoison before, so that page cannot longer go into a pcplist, and soft_offline_page only flags a page as HWPoison if 1) we took the page off a buddy freelist 2) the page was in-use and we migrated it 3) was a clean pagecache. Because of that, a page cannot longer be poisoned and be in a pcplist. Signed-off-by: Oscar Salvador <osalvador@suse.de> --- mm/madvise.c | 4 ---- 1 file changed, 4 deletions(-)
