Merge tag 'signal-for-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace

Pull ptrace update from Eric Biederman:
 "ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT

  Recently I had a conversation where it was pointed out to me that
  SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
  difficult for a tracer to handle.

  Keeping SIGKILL working after the process has been killed is pain from
  an implementation point of view.

  So since the debuggers don't want this behavior let's see if we can
  remove this wart for the userspace API

  If a regression is detected it should only need to be the last change
  that is the reverted. The other two are just general cleanups that
  make the last patch simpler"
