Speaking of which..  I've been having struggling a bit with 

vfs-make-filldir_t-and-struct-kstat-deal-in-64-bit-inode-numbers.patch
nfs-represent-64-bit-fileids-as-64-bit-inode-numbers-on-32-bit-systems.patch

I don't have a good understanding of what the implications are for userspace.
What are the risks and what are the advantages and what the level of urgency
is behind those patches.

Help?
