Everything below drivers/staging/lustre/Kconfig is only sourced if
STAGING is set. You can drop the dependency on STAGING.

The Lustre client does not need a block device - it is a network
filesystem.
The one piece of code that is relevant here relates to a Lustre-optimized
"loop" device that bypasses the VFS, data copying, and DLM locking for use
by swap and such. It would be better instead to make that code conditional
and add a new CONFIG_LUSTRE_LLOOP or similar, and only make that part
dependent
on BLOCK.
Cheers, Andreas

This makes sence. I noticed that this patch has gone into Greg's tree,
so a coming patch
based on this patch is cool?
