[zfs-code] Request for help and advice on cache behaviour

[Ricardo Correia]

Hi,

I'm not sure how to control the ARC on the ZFS port to FUSE.

In the alpha1 release, for testing, I simply set the zfs_arc_max and 
zfs_arc_min variables to 80 MBs and 64 MBs (respectively) to prevent the ARC 
from growing unboundedly.

However, I'm having a problem. A simple run of the following script will cause 
zfs-fuse memory usage to grow almost indefinitely:

for i in `seq 1 100000`;
do
 touch /pool/testdir/$i
done

The problem seems to be that vnodes are getting allocated and never freed.
