- Kernel modules are small pieces of compiled code which can

- many parts of the kernel can be built as modules (by

- useful for infrequently used options which are not required
- for booting. For more information, see the man pages for
- modprobe, lsmod, modinfo, insmod and rmmod.
-
- If you say Y here, you will need to run "make
- modules_install" to put the modules under /lib/modules/

- without waiting for anyone to stop using it (using the -f option to

- CONFIG_SECURITY_LOCKDOWN_LSM or lockdown functionality imposed via

- of the lockdown policy.
-
- !!!WARNING!!! If you enable this option, you MUST make sure that the

- choose to not compress modules at all.)
-
- External modules will also be compressed in the same way during the

-
- For modules inside an initrd or initramfs, it's more efficient to
- compress the whole initrd or initramfs instead.

-
- Please note that the tool used to load modules needs to support the

-config MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS
- bool "Allow loading of modules with missing namespace imports"
- help
- Symbols exported with EXPORT_SYMBOL_NS*() are considered exported in
- a namespace. A module that makes use of a symbol exported with such a
- namespace is required to import the namespace via MODULE_IMPORT_NS().
- There is no technical reason to enforce correct namespace imports,
- but it creates consistency between symbols defining namespaces and

-
-config MODPROBE_PATH

- When kernel code requests a module, it does so by calling
- the "modprobe" userspace utility. This option allows you to
- set the path where that binary is found. This can be changed
- at runtime via the sysctl file
- /proc/sys/kernel/modprobe. Setting this to the empty string

- The kernel and some modules make many symbols available for
- other modules to use via EXPORT_SYMBOL() and variants. Depending
- on the set of modules being selected in your kernel configuration,
- many of those exported symbols might never be used.
-
- This option allows for unused exported symbols to be dropped from

- (especially when using LTO) for optimizing the code and reducing
- binary size. This might have some security advantages as well.

-
