I guess that "requires >= v5.2" may prompt me with the kernel version, and after upgrading the kernel to >=5.2, it was successfully confirmed to be true.
Many instances of golang processes are still running in lower version kernels.So do we have any idea or plan to make it compatible with lower version kernels?
