AFAIK, no admin-level-user tool to get that information, no. But doing a successive balances while incrementing the -dusage= -musage= counts should get you a rough idea (tho it looks like that's what you're trying to avoid by asking for the report in the first place), and I believe it's findable with the lower-level developer tools, I'd guess btrfs-debug-tree. -- Duncan - List replies preferred.
