Subject: [PATCH] config SPRUCE

Hi all!

	As part of the VAMOS[0] research project at the University of
Erlangen we are looking at multiple integrity errors in linux'
configuration system.

	CONFIG_SPRUCE is obsolete since kernel 2.6.26 so this last bit
should be killed as well I guess.

	Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

	Christoph Egger

Subject: [PATCH] Remaining of CONFIG_SPRUCE removal (2.6.26)

CONFIG_SPRUCE was removed from kernel around 2.6.26. Last piece of
relevant code that is still in linux' source tree will be removed by
this patch.
