From 47e431f43b5d879f04a2df645366ca007351ffff Mon Sep 17 00:00:00 2001 From: Oscar Salvador Date: Mon, 14 Dec 2020 19:11:45 -0800 Subject: mm,hwpoison: remove drain_all_pages from shake_page get_hwpoison_page already drains pcplists, previously disabling them when trying to grab a refcount. We do not need shake_page to take care of it anymore.
