   9 config BUSYBOX_CONFIG_MODPROBE_SMALL
  10         bool "Simplified modutils"
  11         default BUSYBOX_DEFAULT_MODPROBE_SMALL
  12         help
  13         Build smaller (~1.5 kbytes), simplified module tools.
  14
  15         This option by itself does not enable any applets -
  16         you need to select applets individually below.
  17
  18         With this option modprobe does not require modules.dep file
  19         and does not use /etc/modules.conf file.
  20         It scans module files in /lib/modules/`uname -r` and
  21         determines dependencies and module alias names on the fly.
  22         This may make module loading slower, most notably
  23         when one needs to load module by alias (this requires
  24         scanning through module _bodies_).
  25
  26         At the first attempt to load a module by alias modprobe
  27         will try to generate modules.dep.bb file in order to speed up
  28         future loads by alias. Failure to do so (read-only /lib/modules,
  29         etc) is not reported, and future modprobes will be slow too.
  30
  31         NB: modules.dep.bb file format is not compatible
  32         with modules.dep file as created/used by standard module tools.
  33
  34         Additional module parameters can be stored in
  35         /etc/modules/$module_name files.

  85         Say 'y' here to enable support for the 'blacklist' command in
  86         modprobe.conf. This prevents the alias resolver to resolve
  87         blacklisted modules. This is useful if you want to prevent your

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

 177         Support checking for tainted modules. These are usually binary
 178         only modules that will make the linux-kernel list ignore your

 186         help
 187         This option causes module loading code to try to mmap
 188         module first. If it does not work (for example,
 189         it does not work for compressed modules), module will be read
 190         (and unpacked if needed) into a memory block allocated by malloc.
 191
 192         The only case when mmap works but malloc does not is when
 193         you are trying to load a big module on a very memory-constrained
 194         machine. Malloc will momentarily need 2x as much memory as mmap.
 195
