| |
When running scftorture as a module, any scf_torture_init() issues will be reflected in the error code from modprobe or insmod, as the case may be. However, these error codes are not available when running scftorture built-in, for example, when using the kvm.sh script. This commit therefore adds WARN_ON_ONCE() to allow distinguishing scf_torture_init() errors when running scftorture built-in.
