Introduce a versatile interface to query auxilary io_uring parameters.
It will be used to close a couple of API gaps, but in this series can
only tell what request and register opcodes, features and setup flags
are available. It'll replace IORING_REGISTER_PROBE but with a much
more convenient interface. Patch 3 for API description.
Can be tested with:
https://github.com/isilence/liburing.git io_uring/query-v1
Note: RFC as I've got a last minute uapi adjustment I want to try.
Pavel Begunkov (3):
io_uring: add helper for *REGISTER_SEND_MSG_RING
io_uring: add macro for features and valid setup flags
io_uring: introduce io_uring querying
