[PATCH v2 0/2] implement timeout update

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

Timeout update is a IORING_OP_TIMEOUT_REMOVE request with timeout_flags
containing a new IORING_TIMEOUT_UPDATE flag. Even though naming may be
confusing, but update and remove are very similar both code and
functionality wise, so doesn't seem necessary to add a new opcode.

Updates don't support offsets, but I don't see a need either. Can
be implemented in the future by passing it in sqe->len.

v2: nits for [2/2] (Jens)

Pavel Begunkov (2):
  io_uring: restructure io_timeout_cancel()
  io_uring: add timeout update
