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

[Ryan Harper]

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.

[Adam Borowski (kilobyte)]

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.
