    GFS2: Expose UUID via sysfs/uevent · 02e3cc70
    Steven Whitehouse authored
    Since we have a UUID, we ought to expose it to the user via sysfs
    and uevents. We already have the fs name in both of these places
    (a combination of the lock proto and lock table name) so if we add
    the UUID as well, we have a full set.
    
    For older filesystems (i.e. those created before mkfs.gfs2 was writing
    UUIDs by default) the sysfs file will appear zero length, and no UUID
    env var will be added to the uevents.
