Peter Zijlstra b6d3d3816c ptrace: Convert ptrace_attach() to use lock guards ...

[ Upstream commit 5431fdd2c1 ]

Created as testing for the conditional guard infrastructure.
Specifically this makes use of the following form:

  scoped_cond_guard (mutex_intr, return -ERESTARTNOINTR,
		     &task->signal->cred_guard_mutex) {
    ...
  }
  ...
  return 0;
