I think Andrew is referring to my team in comment #7 (my NFS exports are on an ext3 partition). I can confirm that mainline kernel 3.2.27-generic does *not* resolve the leak, as I recently noticed the leak again. I think it was a NFSv3 vs. v4 issue, as many of my clients moved back to v3 as an attempt to resolve the issue. But a few rarely-utilized clients remained, and it seems that NFSv4 activity from these clients correlates with memory leakage in idr_layer_cache.

So, I've seen the leak on all the following:

3.2.0-30-generic
3.2.0-29-generic
3.2.27-030227-generic

The last kernel is a vanilla build from the Ubuntu PPA:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2.27-precise/

So, I think that this is an upstream leak, at least in the 3.2.x stable branch.
