description:
When we auto size the vnode cache, make sure we do it *before* we
init vfs so it can the size into account when creating its hash lists.
This means that for a 2GB system, it'll have a default of 65536 buckets
instead of 2048 and when you have 200,000+ vnodes that makes a significant
difference.
