This patches set allows to change the allocation_hint even for an unmounted
filesystem.  It does that using the user space btrfs code.

Because the userspace btrfs code is unaware of the allocation_hint 
if a new (metadata) chunk allocation is required during the changing of
this property, the new chunk is allocated without considering the
allocation_hint ... hint.


Goffredo Baroncelli (3):
  Rename btrfs_device->type to flags
  Rename dev_item.type in flags in the command output.
  Read/change the allocation_hint prop when unmounted
