Subject: Re: [Devel] [PATCH 1/1] Dynamically allocate the loopback device

no, and this is important. Loopback is initialized in fs_initcall which
is called sufficiently before module_init.

I have checked the code and do not see initialization order mistakes
right now. But, from now on, maintainer should pay attention for this
unfortunate consequence :(

Regards,
    Den
