Subject: [RFC v2 0/2] vfs / btrfs: add support for ustat()

From: "Luis R. Rodriguez" <mcgrof@...e.com>

This makes the implementation simpler by stuffing the struct on
the driver and just letting the driver iinsert it and remove it
onto the sb list. This avoids the kzalloc() completely.

Luis R. Rodriguez (2):
  fs/super.c: add new super block sub devices super_block_dev
  btrfs: use the new VFS super_block_dev
