btrfs: extend balance filter usage to take minimum and maximum
Similar to the 'limit' filter, we can enhance the 'usage' filter to accept a range. The change is backward compatible, the range is applied only in connection with the BTRFS_BALANCE_ARGS_USAGE_RANGE flag. We don't have a usecase yet, the current syntax has been sufficient. The enhancement should provide parity with other range-like filters. Signed-off-by: David Sterba <dsterba@suse.com> Signed-off-by: Chris Mason <clm@fb.com>
