Subject: Remove redundant check for PTRACE_LISTEN availability
X-Git-Tag: v4.14~156

Remove redundant check for PTRACE_LISTEN availability

As ptrace.h already ensures that PTRACE_LISTEN is defined,
there is no need to check this fact in other places.

* strace.c (ptrace_restart): Do not check that PTRACE_LISTEN is defined.
