I have found a way around the problem I was having.  The first time I tried
to build the kernel I built lvm into the kernel, but I said "no" to the lvm

Now my question is having lvm report things to /proc will I notice any slow
Just courious.

Thanks for all of the hard work everyone is putting into lvm!!!!!!!

proper kernel source tree.  It was a while ago though, but I'm thinking
that solved it for me.  I believe one of the files included in lvm.c is a
<linux/*whatever*> and that didn't exist or have the proper struct or
