Subject: [GIT PULL] Enable IORING_CQE_F_SOCK_NONEMPTY for accept requests
Hi Linus,
This one was deferred, as it both depended on the net branch and the
io_uring changes for 6.10. Sending it now as both have landed.
This adds support for IORING_CQE_F_SOCK_NONEMPTY for io_uring accept
requests. This is very similar to previous work that enabled the same
hint for doing receives on sockets. By far the majority of the work here
is refactoring to enable the networking side to pass back whether or not
the socket had more pending requests after accepting the current one,
the last patch just wires it up for io_uring.
Not only does this enable applications to know whether there are more
connections to accept right now, it also enables smarter logic for
io_uring multishot accept on whether to retry immediately or wait for a
poll trigger.
Please pull!
