[lvm-devel] [PATCH 2/3] Update lvmcache_update_vg to use vgid as well as vgname.

[Dave Wysochanski]

With duplicate vgnames in a system, vg metadata could get
exported to the wrong lvmcache_vginfo structure.  Use the vg_uuid as
well as the name to lookup the vginfo structure before we store the
metadata.
