Boot-tested under QEMU for Rust x86_64:

Tested-by: Miguel Ojeda <ojeda@kernel.org>

I am seeing the following warning:

    net/sunrpc/svc_xprt.c:874:1: warning: label at end of compound statement is a C23 extension [-Wc23-extensions]
      874 | }
          | ^

It looks like mainline cleans that up in the next commit which was not
backported, so we get to see the intermediate warning here:

  7b31f4daebad ("SUNRPC: rename and refactor svc_get_next_xprt()")

Thanks!

Thanks for the report. e3274026e2ec ("SUNRPC: move all of xprt handling
into svc_xprt_handle()") was only queued for 6.6 as a prerequisite of
c479bde671cb ("sunrpc: defer rq_argp and rq_resp free until after RCU
grace period"), and that fix does not do anything on 6.6: it protects RCU
readers in the nfsd netlink rpc_status interface, which was added in 6.7.

So instead of adding 7b31f4daebad, I dropped the whole chain from the
6.6 queue.
