  19           By default modules.dep contains all dependencies as listed by
  20           the modules.
  21           If you enable this option then we remove implied modules from
  22           the dependencies.
  23           This makes depmod somewhat bigger but generates a smaller
  24           modules.dep file.

  68           This is a special uClinux only memory optimization that lets insmod
  69           load the specified kernel module directly into kernel space, reducing
  70           memory usage by preventing the need for two copies of the module

 132           This is a WIP, while waiting for a common argument parsing
 133           common amongst all BB applets (shell, modprobe, etc...) and
 134           adds around 600 bytes on x86, 700 bytes on ARM. The code is
 135           biggish and uggly, but just works.

 156           Say 'y' here to enable support for the 'blacklist' command in
 157           modprobe.conf. This prevents the alias resolver to resolve
 158           blacklisted modules. This is useful if you want to prevent your
 159           hardware autodetection scripts to load modules like evdev, frame
 160           buffer drivers etc.
