From b467f3ef3c50c4fa8926ca07f7db9a33a645e13a Mon Sep 17 00:00:00 2001 From: Vlastimil Babka Date: Sun, 7 Jun 2020 21:40:31 -0700 Subject: kernel/hung_task convert hung_task_panic boot parameter to sysctl We can now handle sysctl parameters on kernel command line and have infrastructure to convert legacy command line options that duplicate sysctl to become a sysctl alias. This patch converts the hung_task_panic parameter. Note that the sysctl handler is more strict and allows only 0 and 1, while the legacy parameter allowed any non-zero value. But there is little reason anyone would not be using 1.
