Btrfs progs release 6.1

[David Sterba <dsterba@suse.com>]

Hi,

btrfs-progs version 6.1 have been released.

There are new commands that are in the experimental mode until the interface
stabilizes, which means that it's a good time to give feedback or point out
deficiencies. There's no ETA set to remove the experimental status, I think and
hope that the feedback loop could work better if there's something tangible and
ready to test. The code is not the hard part unlike the interfaces and
formatting, this starts at the use case and user input is the important part.

The json output is also kind of experimental but there are tools that want it
now and can give feedback before there's some common format for all commands.
