[PATCH v3 12/13] mm/memory-failure: remove obsolete comment in kill_proc()

From: Miaohe Lin
Date: Wed Jun 12 2024 - 03:24:38 EST


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.
