So the question is, what is user-space going to do? Do any glibc

My goal at the moment is to get folks enabled to the point that they can
start modifying apps to use pkeys without having to patch their kernels.
 I don't have confidence that we can design good high-level userspace
interfaces without seeing some real apps try to use the low-level ones
and seeing how they struggle.

I had some glibc code to do the pkey alloc/free operations, but those
aren't necessary if we're doing it in the kernel.  Other than getting
the syscall wrappers in place, I don't have any immediate plans to do
anything in glibc.

Was there something you were expecting to see?
