The xdp tracepoints for mem id disconnect don't carry information about, why it was not safe_to_remove. The tracepoint page_pool:page_pool_inflight in this patch can be used for extract this info for further debugging. This patchset also adds tracepoint for the pages_state_* release/hold transitions, including a pointer to the page. This can be used for stats about in-flight pages, or used to debug page leakage via keeping track of page pointer and combining this with kprobe for __put_page().
