[net-next PATCH v2 0/2] Change page_pool timeout handling

[Jonathan Lemon <jonathan.lemon@gmail.com>]

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.

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

Jonathan Lemon (2):
  page_pool: do not release pool until inflight == 0.
  page_pool: remove hold/release count from tracepoints
