Hi, Trond

Thanks for the reply. What kind of reclaiming scheme is used by
NFS client and the Linux local file system, say ext2/ext3?
Is it used for reclaiming the inode resources, or for memory
in general (like killing processes)?

Is there any benchmark available to test how many active inodes
a particular system can support?

The same behaviour as for local files: as memory goes low, the
ordinary reclaiming schemes kick in, and all should be hunky-dory. Of
course in the *real world*, ...
