Add a test for the issue that was fixed in "team: avoid NETDEV_CHANGEMTU event when unregistering slave". The test hangs due to a reference count leak without the fix: # make -C tools/testing/selftests TARGETS="drivers/net/team" TEST_PROGS=refleak.sh TEST_GEN_PROGS="" run_tests [...] TAP version 13 1..1 # timeout set to 45 # selftests: drivers/net/team: refleak.sh [ 50.681299][ T496] unregister_netdevice: waiting for dummy1 to become free. Usage count = 3 [ 71.185325][ T496] unregister_netdevice: waiting for dummy1 to become free. Usage count = 3 And passes with the fix: # make -C tools/testing/selftests TARGETS="drivers/net/team" TEST_PROGS=refleak.sh TEST_GEN_PROGS="" run_tests [...] TAP version 13 1..1 # timeout set to 45 # selftests: drivers/net/team: refleak.sh ok 1 selftests: drivers/net/team: refleak.sh Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Acked-by: Stanislav Fomichev <sdf@fomichev.me> Link: https://patch.msgid.link/20260224125709.317574-3-idosch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
