Subject: selftests/mm: use pkey_assert on clone_raw failure in pkey test
Date: Mon, 6 Jul 2026 16:15:57 +0800
Use pkey_assert(0) instead of perror("clone") when clone_raw() fails. The
old path only printed an error and continued; the test now exits via
pkey_assert() on failure so it does not hang or proceed with an invalid
child.
