Ideally speaking, the checks and the setups of those new bits should be coupled with the PCM protocol version check (and the version bump).
But it seems that you've already applied the series, and practically seen, those bits should be either not set or harmless, so let's cross fingers.
Exactly, the current kernel code should skip those new flags, so they are used in alsa-lib only. It's just something like a "reservation" for the kernel space until things are really used there. We can bump the protocol version later (perhaps with other changes).
