Subject: selftests: prctl: return after executing test in child process
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=2cdadb46fb92e2323a148ddcbc88c1a56f99e5fd;p=users%2Fjedix%2Flinux-maple.git

selftests: prctl: return after executing test in child process

The next step after executing the test is a wait, but there is nothing to
wait for in the child, so just return.
