[Devel] [PATCH hci-8.1] ms/um: Set parent death signal for userspace process

[Konstantin Khorenko]

  - The rebase note is misleading: "as mainline does for the winch
    thread". In vz10 the winch thread does not use this helper either,
    because 42b8b00c8ab1a ("um: Use os_set_pdeathsig helper in winch
    thread/process") is not backported.
  - To fix it, either:
    - send 4e5adbe447db3 ("um: Add os_set_pdeathsig helper function") as
      a prerequisite patch (git apply --check on our base is clean), or
    - call prctl(PR_SET_PDEATHSIG, SIGKILL) directly, as upstream does in
      its stub_exe.c.
