This last series for this window adds various misc improvements to BPF, one is to mark registered map and prog types as __ro_after_init, another one for removing cBPF stubs in eBPF JITs and moving the stub to the core and last also improving JITs is to make generated images visible to the kernel and kallsyms, so they can be seen in traces. For details, please have a look at the individual patches.
Thanks a lot!
