Given that, I tend to print > modules in *text address order* and do not need to change it. ok, thanks. If we need to sort all of module symbols, we can use sort command as I wrote in 0/15. > crash> sym -M | grep MODULE | sort # displayed in address order Thanks, Kazu -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/crash-utility Contribution Guidelines: https://github.com/crash-utility/crash/wiki
