Its filename was mm-memory-failure-remove-obsolete-comment-in-kill_proc.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Miaohe Lin Subject: mm/memory-failure: remove obsolete comment in kill_proc() Date: Wed, 12 Jun 2024 15:18:34 +0800 When user sets SIGBUS to SIG_IGN, it won't cause loop now. For action required mce error, SIGBUS cannot be blocked. Also when a hwpoisoned page is re-accessed, kill_accessing_process() will be called to kill the process.
