Eric,

Thanks once more for the patch.  Once I finally got the correct version 
of mkfs.btrfs this looks good.

Reviewed-by: Rich Johnston <rjohnston@sgi.com>

Interesting that the default make install of btrfs-progs did not install 
over my btrfsprogs rpm.

Was running SLES11 SP2 with btrfsprogs-0.19-5.31.1.x86_64.

It did not put mkfs.btrfs in /sbin.  This did however, validate all the 
error paths ;).
