This patchset allows for io_uring zerocopy to support REQ_F_CQE_SKIP, skipping the normal completion notification, but not the zerocopy buffer release notification.
It's an io_uring internal change not altering how it operates with the net layer, you don't need to CC the net list.
This patchset also includes a test to test these changes, and a patch to mini_liburing to enable io_uring_peek_cqe, which is needed for the test.
For the same reason tests should be in liburing, where all io_uring tests are, and the selftest can be dropped. See liburing/test/send-zerocopy.c
