There is a minor problem in lvm.c / lvm_proc_get_info()

lvm_proc_get_info() returns -1 on EOF which results in a bogus EPERM 
returned to user mode. Try a cat /proc/lvm to see the effect.
Returning 0 should indicate the EOF condition.

Trivial patch against 0.6 is below. Obviously this also needs to
be applied against linux/drivers/block/lvm.c
