Ok Jos, i diffed in like swine and found a very very dirty hack!

First, remove the "-D__KERNEL__" from the Makefiles in the tools
directory. Then do the following around the include of <linux/kdev_t.h>
in <linux/lvm.h>:

/* KS : Look out! Following is a bad, bad hack to solve compile
problems         * when for tools with devfs and lvm! */
#if !defined (__KERNEL__)
#define  __KERNEL__ oh_no_no_no
#include <linux/kdev_t.h>
#undef __KERNEL__
#else
#include <linux/kdev_t.h>
#endif

It works for me, hope it helps you!

Ciao
Klaus
