I definitely think we should initialise AF_UNIX sockets earlier. At
least request_module() _can_ work then, if you want it to and you set up
userspace accordingly.

I'm also tempted to reduce the proliferation of modules in drivers/mtd
and turn the various partition options into booleans, though. Your
original patch is close, but I don't think it works in the CONFIG_MTD=m
case. I think we need to modify drivers/mtd/Makefile too, along these
lines:

I'll play with it.
