remember: "indent" is not a fix for bad programming.
- Chapter 10: Configuration-files
+ Chapter 10: Kconfig configuration files
-For configuration options (arch/xxx/Kconfig, and all the Kconfig files),
-somewhat different indentation is used.
+For all of the Kconfig* configuration files throughout the source tree,
+the indentation is somewhat different. Lines under a "config" definition
+are indented with one tab, while help text is indented an additional two
+spaces. Example:
-Help text is indented with 2 spaces.
- tristate CONFIG_BOOM
- default n
- help
- Apply nitroglycerine inside the keyboard (DANGEROUS)
- depends on CONFIG_BOOM
- default y
+config AUDIT
+ bool "Auditing support"
+ depends on NET
- Output nice messages when you explode
+ Enable auditing infrastructure that can be used with another
+ kernel subsystem, such as SELinux (which requires this for
+ logging of avc messages output). Does not do system-call
+ auditing without CONFIG_AUDITSYSCALL.
+Features that might still be considered unstable should be defined as
+dependent on "EXPERIMENTAL":
+config SLUB
+ bool "SLUB (Unqueued Allocator)"
+ ...
+while seriously dangerous features (such as write support for certain
+filesystems) should advertise this prominently in their prompt string:
+config ADFS_FS_RW
+ bool "ADFS write support (DANGEROUS)"
+ depends on ADFS_FS
+ ...
-Generally, CONFIG_EXPERIMENTAL should surround all options not considered
-stable. All options that are known to trash data (experimental write-
-support for file-systems, for instance) should be denoted (DANGEROUS), other
-experimental options should be denoted (EXPERIMENTAL).
