Since Linux 4.16 (to atleast RC2) user space started to excessively trigger cap_sys_module
Here is one example of such and event:
type=SYSCALL msg=audit(02/27/2018 08:06:40.017:74) : arch=x86_64 syscall=ioctl success=no exit=ENOTTY(Inappropriate ioctl for device) a0=0x2 a1=TCGETS a2=0x7fff2d89f8f0 a3=0x55ba203a9010 items=0 ppid=1 pid=423 auid=unset uid=root gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root tty=(none) ses=unset comm=systemd-user-se exe=/usr/lib/systemd/systemd-user-sessions subj=sys.id:sys.role:user_sessions.subj:s0 key=(null)

Any idea what causes this and how to fix it?
