  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.

 146         help
 147           This option causes module loading code to try to mmap
 148           module first. If it does not work (for example,
 149           it does not work for compressed modules), module will be read
 150           (and unpacked if needed) into a memory block allocated by malloc.
 151
 152           The only case when mmap works but malloc does not is when
 153           you are trying to load a big module on a very memory-constrained
 154           machine. Malloc will momentarily need 2x as much memory as mmap.
 155
 156           Choosing N saves about 250 bytes of code (on 32-bit x86).
