Cover letter [PATCH bpf-next 0/9] BPF misc improvements
This series adds various misc improvements to BPF: detection of BPF helper definition misconfiguration for mem/size argument pairs, csum_diff helper also for XDP, various test cases, removal of the recently added pure_initcall(), restriction of the jit sysctls to cap_sys_admin for initns, a minor size improvement for x86 jit in alu ops, output of complexity limit to verifier log and last but not least having the event output more flexible with moving to const_size_or_zero type.
Thanks!
