    afs: Add metadata xattrs · d3e3b7ea
    David Howells authored
    Add xattrs to allow the user to get/set metadata in lieu of having pioctl()
    available.  The following xattrs are now available:
    
     - "afs.cell"
    
       The name of the cell in which the vnode's volume resides.
    
     - "afs.fid"
    
       The volume ID, vnode ID and vnode uniquifier of the file as three hex
       numbers separated by colons.
    
     - "afs.volume"
    
       The name of the volume in which the vnode resides.
    
    For example:
    
    	# getfattr -d -m ".*" /mnt/scratch
    	getfattr: Removing leading '/' from absolute path names
    	# file: mnt/scratch
    	afs.cell="mycell.myorg.org"
    	afs.fid="10000b:1:1"
    	afs.volume="scratch"
