[PATCH v2 0/7] simplify overflow CQE handling

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

Some improvements for overflow posting like replacing GFP_ATOMIC
with GFP_KERNEL in few cases and debug assertions for invariant
violations.

v2: nest another lock to get rid of conditional locking

Pavel Begunkov (7):
  io_uring: fix overflow resched cqe reordering
  io_uring: init overflow entry before passing to tracing
  io_uring: open code io_req_cqe_overflow()
  io_uring: split __io_cqring_overflow_flush()
  io_uring: separate lock for protecting overflow list
  io_uring: avoid GFP_ATOMIC for overflows if possible
  io_uring: add lockdep warning for overflow posting
