Zhangjin,
for your convenience, I've queued your pending series and Thomas's patches in the following order here: 20230709-nolibc-ser2-tom-syscall-configv4
series2, thomas' chmod_net and ioperm patches, your new syscall series, and your tiny config version 4 series.
Thomas and Zhangjin, do not hesitate to let me know if I missed anything. The two series I left aside for now are still just under discussion (output reformating and reorganisation of the arch include files).
We're getting closer to having something done now!
Thanks! Willy
