What's the benefit? The downside is a bit more complexity as you need an
additional callback handler.
synchronize_rcu() can be very slow (its a systemwide operation), and
mmu_shrink() can be called often on a loaded system.
In fact this just shows that vm_list is not a good candidate for rcu;
rcu is useful where most operations are reads, but if we discount stats,
most operations on vm_list are going to be writes.
