[Unionfs] disable unionfs cache?

[Pásztor Lénárd Zoltán]

Hi!

The newest release with 2.6.22.1 kernel works stably for me, thanks for the
fixes!
The cache coherency feature also working fine with the specified mount
option which increments the generation number of the superblock (incgen).

I have multiple servers with low nfs traffic.
I'd love to see if the unionfs do not cache any objects in it's branches, so
every file access means an object-reget.
Is it possible to implement as a mount option?
Or is there any solution to get always the latest filesystem state without
user interaction?

For example if I do a remount with incgen option in every 10 seconds it may
solve the problem but I think it's an ugly hack.
