From d49f2366e98081471dbef5c1bc0da00d10fa0776 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Wed, 12 Jun 2024 15:18:34 +0800 Subject: [PATCH] mm/memory-failure: remove obsolete comment in kill_proc() 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.
