Here is the summary with links:
  - [bpf-next,v2,1/4] bpf: track immediate values written to stack by BPF_ST instruction
    https://git.kernel.org/bpf/bpf-next/c/ecdf985d7615
  - [bpf-next,v2,2/4] selftests/bpf: check if verifier tracks constants spilled by BPF_ST_MEM

  - [bpf-next,v2,3/4] bpf: BPF_ST with variable offset should preserve STACK_ZERO marks
    https://git.kernel.org/bpf/bpf-next/c/31ff2135121c
  - [bpf-next,v2,4/4] selftests/bpf: check if BPF_ST with variable offset preserves STACK_ZERO
