[PATCH v2 0/4] clodkid and abs mode CQ wait timeouts

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

Patch 3 allows the user to pass IORING_ENTER_ABS_TIMER while waiting
for completions, which makes the kernel to interpret the passed timespec
not as a relative time to wait but rather an absolute timeout.

Patch 4 adds a way to set a clock id to use for CQ waiting.

Tests: https://github.com/isilence/liburing.git abs-timeout

v2: Add clock id registration
    Adjustment using iowq->timeout in Patch 2

Pavel Begunkov (4):
  io_uring/napi: refactor __io_napi_busy_loop()
  io_uring/napi: postpone napi timeout adjustment
  io_uring: add absolute mode wait timeouts
  io_uring: user registered clockid for wait timeouts
