  14           Simplified modutils.
  15
  16           With this option modprobe does not require modules.dep file
  17           and does not use /etc/modules.conf file.
  18           It scans module files in /lib/modules/`uname -r` and
  19           determines dependencies and module alias names on the fly.
  20           This may make module loading slower, most notably
  21           when one needs to load module by alias (this requires
  22           scanning through module _bodies_).
  23
  24           At the first attempt to load a module by alias modprobe
  25           will try to generate modules.dep.bb file in order to speed up
  26           future loads by alias. Failure to do so (read-only /lib/modules,
  27           etc) is not reported, and future modprobes will be slow too.
  28
  29           NB: modules.dep.bb file format is not compatible
  30           with modules.dep file as created/used by standard module tools.
  31
  32           Additional module parameters can be stored in
  33           /etc/modules/$module_name files.
  34
  35           Apart from modprobe, other utilities are also provided:
  36           - insmod is an alias to modprobe
  37           - rmmod is an alias to modprobe -r
  38           - depmod generates modules.dep.bb

 134           This option causes module loading code to try to mmap
 135           module first. If it does not work (for example,
 136           it does not work for compressed modules), module will be read
 137           (and unpacked if needed) into a memory block allocated by malloc.
 138
 139           The only case when mmap works but malloc does not is when
 140           you are trying to load a big module on a very memory-constrained
 141           machine. Malloc will momentarily need 2x as much memory as mmap.
