FWIW, these warnings are expected ATM and don't have anything to do with
btrfs.
They relate to kernel changes that will eventually result in increased
strictness and security (hdparm won't be able to send suspend commands to
a single partition, for instance, when it'll obviously apply to the whole
drive), but are for now simply warnings, when whole-device commands are
sent to a single partition instead of the whole device, thus allowing
time for the necessary changes in userspace apps to be made.
There was an article about it in the LWN weekly edition some weeks ago.
