====================
page_pool: followup changes to restore tracepoint features

This patchset is a followup to Jonathan patch, that do not release
pool until inflight == 0. That changed page_pool to be responsible for
its own delayed destruction instead of relying on xdp memory model.

As the page_pool maintainer, I'm promoting the use of tracepoint to
troubleshoot and help driver developers verify correctness when
converting at driver to use page_pool. The role of xdp:mem_disconnect
have changed, which broke my bpftrace tools for shutdown verification.
With these changes, the same capabilities are regained.
