From b94bf594cf8ed67cdd0439e70fa939783471597a Mon Sep 17 00:00:00 2001 From: Myungho Jung Date: Wed, 19 Apr 2017 15:24:50 -0700 Subject: timer/sysclt: Restrict timer migration sysctl values to 0 and 1 timer_migration sysctl acts as a boolean switch, so the allowed values should be restricted to 0 and 1. Add the necessary extra fields to the sysctl table entry to enforce that.
