Hi Andrii, I love your patch! Perhaps something to improve: [auto build test WARNING on bpf-next/master] url: https://github.com/0day-ci/linux/commits/Andrii-Nakryiko/Integrate-kernel-module-BTF-support/20201110-095309 base: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git

[PATCH v4 bpf-next 4/5] bpf: load and verify kernel module BTFs

2020-11-09 Thread Andrii Nakryiko
Add kernel module listener that will load/validate and unload module BTF. Module BTFs gets ID generated for them, which makes it possible to iterate them with existing BTF iteration API. They are given their respective module's names, which will get reported through GET_OBJ_INFO API. They are also
