[Bug 1666705] Re: btrfs-debug-tree --uuid doesn't work

[Adam Borowski]

A rm-fix has been released.  btrfs-debug-tree has been deprecated in
-progs 4.4, removed in 4.16, we're on 5.1 now.

So any bugs in btrfs-debug-tree are now gone, with btrfs-debug-tree
itself.

** Changed in: btrfs-progs (Ubuntu)
       Status: New => Fix Released

Title:
  btrfs-debug-tree --uuid doesn't work

Status in btrfs-progs package in Ubuntu:
  Fix Released

Bug description:
  Running btrfs-debug-tree --uuid /dev/vdb returns only the program version, nothing about the UUID.
  I can correctly see the UUID in the --root output and others but --uuid does not return that value.
