In case linux banner can not be found in vmlinux for some reason. The fallback chcking of "Linux version" failed for kernel 7.x with below error msg: WARNING: kernel version inconsistency between vmlinux and dumpfile crash: incompatible arguments: vmlinux is not SMP -- vmcore is SMP Not sure how to reproduce, tested by forcing get_linux_banner_from_vmlinux to return false. Add "Linux version 7" to fix it.

I hesitated to add a future number but I agree that it is more often then the old days :) Let's see how Tao Liu prefer since he is maintaining the repo. > >> continue; >> if (strstr(buffer, kt->proc_version)) { > >
