[linux-lvm] proposed change in lvm_dir_cache.c



The patch below will work around a problem with the LVM scan code.
If no valid block devices could be found using /proc/partitions 
the LVM scan code will fallback to scan /dev.

This happened to me when compiling devfs in the kernel without
mounting it in /dev (by using the devfs=nomount option).
In this case /proc/partitions returns block device names
relative to the devfs mount point.
