From: Kui-Feng Lee <thinker.li@gmail.com> mainline inclusion from mainline-v6.9-rc1 commit df9705eaa0bad034dad0f73386ff82f5c4dd7e24 category: feature bugzilla: https://atomgit.com/openeuler/kernel/issues/8335 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ---------------------------------------------------------------------- The "i" here is always equal to "btf_type_vlen(t)" since the "for_each_member()" loop never breaks.
