Subject: rcutorture: Add --no-initrd argument to kvm.sh
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=73931b5ee92d013b7b7d62927cca2a8dfdf3a9d3;p=linux-beck.git

rcutorture: Add --no-initrd argument to kvm.sh

This commit adds the --no-initrd argument to kvm.sh, which permits
initrd to be contained in a root partition specified by the --bootargs
argument.  Without --no-initrd, the kernel build expects an initrd
directory in the same rcutorture directory that contains bin and configs.
