garp: remove last synchronize_rcu() call
When removing last vlan from a device, garp_uninit_applicant() calls synchronize_rcu() to make sure no user can still manipulate struct garp_applicant before we free it. Use call_rcu() instead, as a step to further net_device dismantle optimizations. Add the temporary garp_cleanup_module() function to make sure no pending call_rcu() are left at module unload time [ this will be removed when kfree_rcu() is available ] Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
