I don't see any real reason why that
err = bdi_init(&noop_backing_dev_info);
couldn't just be done very early. Maybe as the first call in
driver_init(), before the whole devtmpfs_init() etc.
I've checked the dependencies and cgroups (which are the only non-trivial
dependency besides per-CPU infrastructure) are initialized early enough so
it should work fine. So let's try that.
Attached patch boots for me. Guys, who was able to reproduce the failure: Can
you please confirm this patch fixes your problem?
