[LTP] [PATCH v1] mount08.c: SKIP test if selinux is running

Hi,

+1, I was going to write the same (remember: often more useful commit message is
not *what* you change, but *why* your did the change).

Also, test under SELinux returns EACCES instead of ENOENT:

mount08.c:32: TFAIL: mount(/proc/130541/fd/4) expected ENOENT: EACCES (13)

Why not keep the test just update errno for SELinux?

In setup:
static int exp_errno = ENOENT;

	if (tst_selinux_enforcing())
		exp_errno = EACCES;

Please don't use upper case. Also SELinux is not "running" but enabled
in enforce mode. If test should be really skip I would use:

	tst_brk(TCONF, "skip test due SELinux enforce");

Kind regards,
