History
Jeff Roberson 228ea9d212 - Don't recycle vnodes anymore. Free them once they are dead. getnewvnode 
now always allocates a new vnode.
 - Define a new function, vnlru_free, which frees vnodes from the free list.
   It takes as a parameter the number of vnodes to free, which is
   wantfreevnodes - freevnodes when called from vnlru_proc or 1 when
   called from getnewvnode().  For now, getnewvnode() still tries to reclaim
   a free vnode before creating a new one when we are near the limit.
 - Define a function, vdestroy, which handles the actual release of memory
   and teardown of locks, etc.  This could become a uma_dtor() routine.
 - Get rid of minvnodes.  Now wantfreevnodes is 1/4th the max vnodes.  This
   keeps more unreferenced vnodes around so that files which have only
   been stat'd are less likely to be kicked out of the system before we
   have a chance to read them, etc.  These vnodes may still be freed via
   the normal vnlru_proc() routines which may some day become a real lru.
