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

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

 174           By adding module symbols to the kernel symbol table, Oops messages
 175           occuring within kernel modules can be properly debugged. By enabling
