It works correctly for me:
fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
open("/selinux/disable", O_RDONLY|O_LARGEFILE) = -1 EACCES (Permission denied)
You got EACCES rather than EINVAL, so your test didn't reach the same
point in the code path. Try it as root (and with appropriate SELinux
role/domain if under -strict or -mls).
write(2, "cat: ", 5cat: ) = 5

Try running with strace so you can see the open syscall.
