SVN rev 187460 on 2009-01-20 04:21:21Z by mckay
Add a limit on namecache entries.
In normal operation, the number of cache entries is roughly equal to the
number of active vnodes. However, when most of the recently accessed
vnodes have many hard links, the number of cache entries can be 32000
times as large, exhausting kernel memory and provoking a panic in
kmem_malloc().
