Subject: [PATCH v1 0/2] io_uring zc rx single shot recvzc

Currently only multishot recvzc requests are supported in io_uring zc
rx, but sometimes there is a need to do a single recvzc e.g. peeking at
some data in the socket.

In this series, add single shot recvzc request and a selftest for the
feature.

  io_uring/zcrx: add single shot recvzc
  io_uring/zcrx: add selftest case for single shot recvzc
