From f7d665627e103e82d34306c7d3f6f46f387c0d8b Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 27 Jul 2016 11:42:38 +0100 Subject: x86/syscalls/64: Add compat_sys_keyctl for 32-bit userspace x86_64 needs to use compat_sys_keyctl for 32-bit userspace rather than calling sys_keyctl(). The latter will work in a lot of cases, thereby hiding the issue.
