From 86b9eea230edf4c67d4d4a70fba9b74505867a25 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Wed, 9 May 2018 10:13:40 -0700 Subject: x86/pkeys/selftests: Stop using assert() If we use assert(), the program "crashes". That can be scary to users, so stop doing it. Just exit with a >0 exit code instead.
