Subject: [net-next PATCH v3 0/1] Change page_pool timeout handling

It isn't safe to remove the page pool until all in-flight pages 
are returned.  If the pages are handed up the stack, it might be
a while before they are returned.

The page pool can also be used independently of xdp, so it shouldn't
be depending on timeout handling from the xdp memory model.  Change
things around so the pool handles its own timeout.

v3:
 - restore tracepoint handling, use atomic_inc_return instead.

v2:
 - fix wording in commit log
 - fix compile error for !PAGE_POOL case
 - revise tracepoint handling

Jonathan Lemon (1):
  page_pool: do not release pool until inflight == 0.
