The __sz arguments are verifier-bounded to the size of an actual BPF object, the kfunc is only reachable from a privileged scheduler's init_cids, and a failed allocation lands in the existing NULL bail which aborts the enable cleanly. Reordering wouldn't buy anything real. No change. Thanks. -- tejun
