From 52e6985f2c916ff0bb84b0b642cac7b7e6b8efae Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Tue, 10 Mar 2020 13:33:32 +0100 Subject: [PATCH] seccomp: Add missing compat_ioctl for notify commit 3db81afd99494a33f1c3839103f0429c8f30cb9d upstream. Executing the seccomp_bpf testsuite under a 64-bit kernel with 32-bit userland (both s390 and x86) doesn't work because there's no compat_ioctl handler defined. Add the handler.
