Comment (by torry):

 Reading the comments from the linked lwn thread:

 ''you can make use of IORING_OP_POLL_ADD to poll all 1,000 network
 connections via the uring, and then use IORING_OP_READV to read only from
 the connections that are ready, using a smaller number of buffers than
 there are connections.

 That's basically the same work level as epoll + read, but with both the
 epoll and the read being done asynchronously.''
