Subjecta lot of used inode in 2.1.x kernels
Running a find over the whole fs in 2.0.x and in a 2.1.x show differences:

2.0.33:

andrea@ark:~$ cat /proc/sys/kernel/inode-nr
432 337

2.1.110-pre2:

andrea@dragon:~$ cat /proc/sys/fs/inode-nr
4112 16
andrea@dragon:~$ cat /proc/sys/fs/inode-max
4096

At first how can be possible that the number of allocated inodes is
greater than the max in 2.1.110?

As second is there a way to avoid the use of so many inodes in 2.1.x
kernels? And why 2.1.x leave so many inode used?

So many inode allocated should help a lot to make not happy low memory
machines (I think this is the first cause of the find />/dev/null
slowdown at second launch on 2.1.x with little ram)...
