It makes it possible to make informed decisions about memory allocation and to find regressions and leaks. Report memory use of page pools. Report both number of references and bytes held.

Together with the inflight / memory use reporting this can serve as a replacement for the warning about leaked page pools we currently print to dmesg. Example output for a fake leaked page pool using some hacks in netdevsim (one "live" pool, and one "leaked" on the same dev): $ ./cli.py --no-schema --spec netlink/specs/netdev.yaml \ --dump page-pool-get [{'id': 2, 'ifindex': 3}, {'id': 1, 'ifindex': 3, 'destroyed': 133, 'inflight': 1}] Tested-by: Dragos Tatulea <dtatulea@nvidia.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Acked-by: Jesper Dangaard Brouer <hawk@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Petr Oros <poros@redhat.com>
