[Note that I'm just a btrfs user and list regular, not a dev, and that my own use-case doesn't involve subvolumes, tho I played with them a bit when I first got into btrfs, so my practical subvolume management knowledge is limited. But based on current git's manpages...] The closest thing in git-master, based on my build from a few days ago, is btrfs subvolume find-new. That lists the recently modified files since <generation>, where generation is fed to the command, with a subvolume's current generation obtainable btrfs subvolume list using its -g option. (btrfs subvolume show might also list current gen, the manpage is vague on what information it shows, and without local subvolumes to test it with...) -- Duncan - List replies preferred.
