See patch #2 for full description and justification. Changes in this dataset support having bpf_spinlock, kptr, rb_tree nodes and other "special" variables as global variables. Combining this with libbpf's existing support for multiple custom .data.* sections allows BPF programs to utilize multiple spinlock/rbtree_node/kptr variables in a pretty natural way by just putting all such variables into separate data sections (and thus ARRAY maps). v1->v2: - address Stanislav's feedback, adds acks. ==================== Acked-by: Kumar Kartikeya Dwivedi Signed-off-by: Alexei Starovoitov --- 7d8d535546a0ac03d7949881ef23bd2c903d19be
