| H A D | page_pool.h | 32c28f7e413981c7dd4a3ad9bbb1151e4b654261 Tue Jun 18 08:06:03 CDT 2019 Jesper Dangaard Brouer <brouer@redhat.com> page_pool: add tracepoints for page_pool with details need by XDP
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().
