The quilt patch titled Subject: mm-hwpoison-kill-procs-if-unmap-fails-v2 has been removed from the -mm tree. Its filename was mm-hwpoison-kill-procs-if-unmap-fails-v2.patch This patch was dropped because it was folded into mm-hwpoison-kill-procs-if-unmap-fails.patch ------------------------------------------------------ From: Miaohe Lin <linmiaohe@xxxxxxxxxx> Subject: mm-hwpoison-kill-procs-if-unmap-fails-v2 Date: Tue, 23 Aug 2022 11:23:45 +0800 If try_to_unmap() fails, the hwpoisoned page still resides in the address space of some processes. We should kill these processes or the hwpoisoned page might be consumed later. collect_procs() is always called to collect relevant processes now so they can be killed later if unmap fails.
