Subject: [PATCH net-next 0/2] minor tcp io_uring zc optimisations

Patch 1 is a simple cleanup, patch 2 gives removes 2 atomics from the
io_uring zc TCP submission path, which yielded extra 0.5% for my
throughput CPU bound tests based on liburing/examples/send-zerocopy.c

Pavel Begunkov (2):
  net/tcp: don't peek at tail for io_uring zc
  net/tcp: optimise io_uring zc ubuf refcounting
