This is the second series for the plan, that adds syscall common attrs support for LINK_CREATE of tracing prog and cgroup prog. BTW, address Andrii's review [1] in patch 5: 1. Change if (!OPTS_ZEROED(opts, iter_info_len)) to if (!OPTS_ZEROED(opts, log_opts)). 2. Add comment to iter_info and iter_info_len that they are deprecated, and use iter.info and iter.len instead.
