Below you can see another iteration. I tried to address all the cwillu
requests, which to me make sense.
I thought a lot about chunk/disks vs disk/chunks, and I reached the
conclusion that we could need both. In order to avoid a too long and
redundant output, my idea is to have three different commands:
1) btrfs filesystem df <path> -> which show what it is called
summary
2) btrfs filesystem disk-usage <path> -> which show what is called
"Detail"
3) btrfs device disk-usage <path> -> which is like 2) but grouped
by disk instead of chunks.
This is an idea about which I want some comments. The example below
show the latest results. I want to point out that I was not able to
show the chunk usage per disk, because I don't have this information.
The patches are not shaped to be showed, however the code is pullable from
