Dmitry, is it possible to update configs for linux-next.git , for
we want to test a big change in LSM which will go to Linux 5.1 ?

TOMOYO security module (CONFIG_SECURITY_TOMOYO=y) can now coexist with
SELinux/Smack/AppArmor security modules, and SafeSetID security module
(CONFIG_SECURITY_SAFESETID=y) was added. Testing with these modules also
enabled might find something...
