[PATCH 0/8] a fix + cancellation unification

[Pavel Begunkov <asml.silence@gmail.com>]

I suggest for 1/8 to go for current, and the rest are for next.
Patches 2-8 finally unify how we do task and files cancellation removing
boilerplate and making it easier to understand overall. As a bonus to it
->inflight_entry is now used only for iopoll, probably can be put into a
union with something and save 16B of io_kiocb if that would be needed.

Pavel Begunkov (8):
  io_uring: close a small race gap for files cancel
  io_uring: further deduplicate #CQ events calc
  io_uring: account per-task #requests with files
  io_uring: explicitly pass tctx into del_task_file
  io_uring: draft files cancel based on inflight cnt
  io_uring: remove old files cancel mechanism
  io_uring: cleanup task cancel
  io_uring: kill not used anymore inflight_lock
