Would it be possible to try out this experimental patch which
gets some stats from the dentry cache ?

Patch 1: dcache_stats.patch
	- shows some dentry cache stats in /proc/meminfo.

Patch 2: cache_shrink_stats.patch (currently in mm)
	- applies on top of the 1st patch; shows the of shrinking of
	slab caches in /proc/slabinfo.

The patches are against 2.6.16-git8. I have just verified that these
work on x86_64. Haven't really stress tested to check if they hold for
reasonable time.
