Hi Alan, Thanks for taking a look at this. I've been following your related effort to allow /sys/kernel/btf/vmlinux as a module in support of small systems with kernel-size constraints, and wondered how this series might affect that work? Such support would be well-received in the embedded space when it happens, so am keen to understand. Thanks, Tony
