Maybe, but this was not invented in DM/MD camp:-) Probably Kay or Greg can answer why it was done this way? For DM it just added links to be proper user of it, see http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f165921df46a977e3561f1bd9f13a348441486d1 Anyway, it is /sys/block - so it represents block devices. If btrfs internally creates some virtual _block_ device for its pool, it should present it here too with slaves/holders. If not, why it should create any links there?
