syzbot ci has tested the following series
[v1] bpf: Prep patches for static stack liveness.
https://lore.kernel.org/all/20260401021635.34636-1-alexei.starovoitov@gmail.com
* [PATCH bpf-next 1/6] bpf: Do register range validation early
* [PATCH bpf-next 2/6] bpf: Sort subprogs in topological order after check_cfg()
* [PATCH bpf-next 3/6] selftests/bpf: Add tests for subprog topological ordering
* [PATCH bpf-next 4/6] bpf: Add compute_const_regs() and prune_dead_branches() passes
* [PATCH bpf-next 5/6] bpf: Move verifier helpers to header
* [PATCH bpf-next 6/6] bpf: Add helper and kfunc stack access size resolution
and found the following issue:
