Speaking of which, Bruce I have a question.

There are a few files in include/linux/ that define xdr definitions
these are used by exportfs nfs and nfsd. Some of it gets exposed
to filesystems. With the pNFS tree we are adding lots more of these,
specifically I'm now to move the pnfs_osd_xdr stuff as well, and blocks.

Could I open up a new  include/linux/exportfs/ folder and put there any thing
xdr and exportfs related?

What should be the scope of the move, should any include/linux/ common
files used both by nfs & nfsd be moved there?

Thanks
Boaz
