SubjectDcache hash distrubition patches
Thanks to Andi for the distribution count patches. I did some quick
numbers with this, just by running "find / | xargs ls -l > /dev/null"
to populate the cache, then dumped the numbers out.

larry:~# grep dentry /proc/slabinfo
dentry_cache 880531 884880 160 36870 36870 1 : 248 124

count length
444569 0
381295 1
163442 2
46937 3
10042 4
1747 5
253 6
30 7
5 8

Conclusion: the hash distribution (for this simple test) looks fine
to me.
