Bug description:
  If I have a multi-device btrfs filesystem, and I plug it in via some
  removable interface (for example, USB3), it will automatically mount
  on the desktop multiple times.  For example, if I have a filesystem
  labeled FooBar on /dev/sdb /dev/sdc /dev/sdd and /dev/sde, it will be
  mounted as /media/FooBar, /media/FooBar1, /media/FooBar2, and
  /media/FooBar3.  It should show up only once.

  It seems like everything still basically works, but I didn't test
  writing to said filesystem under the different aliases.
