Or just make sure that noop_backing_dev_info is fully initialized before it's used.
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?
It does for me.
Thanks for confirmation! I'll send the patch with proper tags etc. and also push it to Linus if nobody objects.
