Hi,

btrfs-progs 4.5-rc1 have been released. The ETA for final release is this
Friday, so please test and report if you find problems. Small fixes or
documentation updates are welcome.

Please apply this patchset. Especially [1/5]~[4/5] fix
the regressions caused by the following commit.

commit 176aeca9a148 ("btrfs-progs: add getopt stubs where needed")

I read whole this commit carefully and probably fixed
all problems in this commit by 1a521af, c742deb,
and this patchset.

"sub get-default" does't work from the following commit.

commit 176aeca9a148 ("btrfs-progs: add getopt stubs where needed")

* actual result

  ==================================================
  # ./btrfs sub get-default /btrfs
  btrfs subvolume get-default: too few arguments
  usage: btrfs subvolume get-default <path>

      Get the default subvolume of a filesystem
  ==================================================

* expected result

  ==================================================
  # btrfs sub get-default /btrfs
  ID 5 (FS_TREE)
  ==================================================
