> .long runqueues > .long 3264 > .long 388 Just to be sure, there seems to be a little discrepancy. The size of runqueues (struct rq) in the latest bpf-next is 3456 instead of 3264, when compiled by both clang 18 and GCC. This is correctly reflected in the BTF generated by both compilers. Is the size of struct rq different in your testing machine?
