It may not be related to cloop of course, but it would reduce the number
of variables for us to have an how-to-reproduce that doesn't involve
running kernel code outside the mainline kernel. If that's the only way
to reproduce we simply have to look into the whole cloop code first,
before we can actually look again into the mainline kernel code for
this.
