14 ---help---
15 Some of the various things that Linux supports (such as network
16 drivers, file systems, network protocols, etc.) can be in a state
17 of development where the functionality, stability, or the level of
18 testing is not yet high enough for general use. This is usually
19 known as the "alpha-test" phase among developers. If a feature is
20 currently in alpha-test, then the developers usually discourage
21 uninformed widespread use of this feature by the general public to
22 avoid "Why doesn't this work?" type mail messages. However, active
23 testing and use of these systems is welcomed. Just be aware that it
24 may not meet the normal level of reliability or it may fail to work
25 in some special cases. Detailed bug reports from people familiar
26 with the kernel internals are usually welcomed by the developers
27 (before submitting bug reports, please read the documents
28 <file:README>, <file:MAINTAINERS>, <file:REPORTING-BUGS>,
29 <file:Documentation/BUG-HUNTING>, and
30 <file:Documentation/oops-tracing.txt> in the kernel source).
31
32 This option will also make obsoleted drivers available. These are
33 drivers that have been replaced by something else, and/or are
34 scheduled to be removed in a future kernel release.
35
36 Unless you intend to help test and develop a feature or driver that
37 falls into this category, or you have a situation that requires
38 using these features, you should probably say N here, which will
39 cause the configurator to present you with fewer choices. If
40 you say Y here, you will be offered the choice of using features or
41 drivers that are currently considered to be in the alpha-test phase.

444 help
445 The shmem is an internal filesystem used to manage shared memory.
446 It is backed by swap and manages resource limits. It is also exported
447 to userspace as tmpfs if TMPFS is enabled. Disabling this
448 option replaces shmem and tmpfs with the much simpler ramfs code,
449 which may be appropriate on small systems without swap.

455 Disabling this replaces the advanced SLAB allocator and
456 kmalloc support with the drastically simpler SLOB allocator.
457 SLOB is more space efficient but does not scale well and is
458 more susceptible to fragmentation.

490config MODULES
491 bool "Enable loadable module support"
492 help
493 Kernel modules are small pieces of compiled code which can
494 be inserted in the running kernel, rather than being
495 permanently built into the kernel. You use the "modprobe"
496 tool to add (and sometimes remove) them. If you say Y here,
497 many parts of the kernel can be built as modules (by
498 answering M instead of Y where indicated): this is most
499 useful for infrequently used options which are not required
500 for booting. For more information, see the man pages for
501 modprobe, lsmod, modinfo, insmod and rmmod.
502
503 If you say Y here, you will need to run "make
504 modules_install" to put the modules under /lib/modules/
505 where modprobe can find them (you may need to be root to do
506 this).

513 help
514 Without this option you will not be able to unload any
515 modules (note that some modules may not be unloadable
516 anyway), which makes your kernel slightly smaller and
517 simpler. If unsure, say Y.

520 bool "Forced module unloading"
521 depends on MODULE_UNLOAD && EXPERIMENTAL
522 help
523 This option allows you to force a module to unload, even if the
524 kernel believes it is unsafe: the kernel will remove the module
525 without waiting for anyone to stop using it (using the -f option to
526 rmmod). This is mainly for kernel developers and desperate users.
527 If unsure, say N.

533 Usually, you have to use modules compiled with your kernel.
534 Saying Y here makes it sometimes possible to use modules
535 compiled for different kernels, by adding enough information
536 to the modules to (hopefully) spot any changes which would
537 make them incompatible with the kernel you are running. If
538 unsure, say N.

544 Modules which contain a MODULE_VERSION get an extra "srcversion"
545 field inserted into their modinfo section, which contains a
546 sum of the source files which made it. This helps maintainers
547 see exactly which source was used to build a module (since
548 others sometimes change the module source without updating
549 the version). With this option, such a "srcversion" field
550 will be created for all modules. If unsure, say N.

555 help
556 Normally when you have selected some parts of the kernel to
557 be created as kernel modules, you must load them (using the
558 "modprobe" command) before you can use them. If you say Y
559 here, some parts of the kernel will be able to load modules
560 automatically: when a part of the kernel needs a module, it
561 runs modprobe with the appropriate arguments, thereby
562 loading the module if it is available. If unsure, say Y.
