From 801dd57bd1d8c2c253f43635a3045bfa32a810b3 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Mon, 15 Jun 2020 10:33:14 +0300 Subject: io_uring: cancel by ->task not pid For an exiting process it tries to cancel all its inflight requests. Use req->task to match such instead of work.pid. We always have req->task set, and it will be valid because we're matching only current exiting task. Also, remove work.pid and everything related, it's useless now. Reported-by: Eric W.
