4.16-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx> [ Upstream commit 86b9eea230edf4c67d4d4a70fba9b74505867a25 ] 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.
