Re: dentry cache leak? Re: rsync out of memory 2.6.8-rc2

[Klaus Dittrich]

I applied your patch to 2.6.8-rc-bk10 and the system survied 
three concurrent du -s started each started with a delay.

Conspicuous is that memory usage (xosview) does not go above 1.5GB now.
Here is a snapshoot of cat/proc/vmstat taken at a time when memory usage
has stagnated.
