Subject: ptrace: __ptrace_unlink: use the ptrace_reparented() helper
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Currently __ptrace_unlink() checks list_empty(->ptrace_list) to figure out
whether the child was reparented. Change the code to use ptrace_reparented()
to make this check more explicit and consistent.
No functional changes.
