Subject: [PATCH 0/2] don't use pid for request cancellation

Cancel requests of an extiting task based on ->task address. As
reported by Eric W. Biederman, using pid for this purpose is not
right.

note: rebased on top of "cancel all" patches

Pavel Begunkov (2):
  io_uring: lazy get task
  io_uring: cancel by ->task not pid
