  20           Simplified modutils.
  21
  22           With this option modprobe does not require modules.dep file
  23           and does not use /etc/modules.conf file.
  24           It scans module files in /lib/modules/`uname -r` and
  25           determines dependencies and module alias names on the fly.
  26           This may make module loading slower, most notably
  27           when one needs to load module by alias (this requires
  28           scanning through module _bodies_).
  29
  30           At the first attempt to load a module by alias modprobe
  31           will try to generate modules.dep.bb file in order to speed up
  32           future loads by alias. Failure to do so (read-only /lib/modules,
  33           etc) is not reported, and future modprobes will be slow too.
  34
  35           NB: modules.dep.bb file format is not compatible
  36           with modules.dep file as created/used by standard module tools.
  37
  38           Additional module parameters can be stored in
  39           /etc/modules/$module_name files.
  40
  41           Apart from modprobe, other utilities are also provided:
  42           - insmod is an alias to modprobe
  43           - rmmod is an alias to modprobe -r
  44           - depmod generates modules.dep.bb
  45
  46           As of 2008-07, this code is experimental. It is 14kb smaller
  47           than "non-small" modutils.

 128           Support module loading for 2.2.x and 2.4.x Linux kernels.
 129           This increases size considerably. Say N unless you plan
 130           to run ancient kernels.

 136         help
 137           This option causes module loading code to try to mmap
 138           module first. If it does not work (for example,
 139           it does not work for compressed modules), module will be read
 140           (and unpacked if needed) into a memory block allocated by malloc.
 141
 142           The only case when mmap works but malloc does not is when
 143           you are trying to load a big module on a very memory-constrained
 144           machine. Malloc will momentarily need 2x as much memory as mmap.
 145
 146           Choosing N saves about 250 bytes of code (on 32-bit x86).

 163           this feature, module symbols will always be added to the kernel symbol
 164           table for proper debugging support. If you are not interested in
 165           Oops messages from kernel modules, say N.

 172           This is a special uClinux only memory optimization that lets insmod
 173           load the specified kernel module directly into kernel space, reducing

 182           Enabling this, one would be able to get a load map
