(I know... I did it for statx; I'm wondering if that was a bad precedent, and/or if it being a syscall makes it a different situation...). I don't know when we ever deprecate or remove this stuff. If you use packaged kernels, you'll get updated headers pretty quickly, right, or on a devel box you might install your own? Not trying to be difficult, just trying to make sure we have a consistent plan for new interfaces like this...
