RE: [PATCH bpf-next] xsk, net: make sock_def_readable() have external linkage

XDP sockets use the default implementation of struct sock's
sk_data_ready callback, which is sock_def_readable(). This function is
called in the XDP socket fast-path, and involves a retpoline. By
letting sock_def_readable() have external linkage, and being called
directly, the retpoline can be avoided.

I think this is fine but curious were you able to measure the
difference with before/after pps or something?
