[David Sterba]

Hi,

btrfs-progs 4.7.3 have been released, bugfix release. There are some minor
fixes, notably the free-space-tree compat status was wrong, see [1] for more.
Some fuzzer bugs have been fixed, but there are still several open.

Changes:
  * fixed free space tree compat status
  * check: low-mem mode: handle partially dropped snapshots
  * dump-super: consolidate options for superblock copy
  * tree-stats: check mount status
  * subvol delete: handle verbosity option
  * defrag: print correct error string
  * mkfs: fix reading rotational status
  * other:
    * UBSAN build option
    * documentation updates
    * enhanced tests: convert, fuzzed images, more tools to run on fuzzed
      images
