History
Poul-Henning Kamp 6c325a2a21 Currently (almost) all filesystems maintain a local inode hash table 
to get from (mount + inode) to vnode.  These tables are mostly
copy&pasted from UFS, sized based on desiredvnodes and therefore
quite large (128K-512K).  Several filesystems are buggy enough that
they allocate the hash table even before they know if they will
ever be used or not.

Add "vfs_hash", a system wide hash table, which will replace all
the per-filesystem hash-tables.

The fields we add to struct vnode will more or less be saved in
the respective filesystems inodes.

Having one central implementation will save code and will allow us
to justify the complexity of code to dynamically (re)size the hash
at a later point.
