 remember: "indent" is not a fix for bad programming.

-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.

+          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
+        depends on EXPERIMENTAL && !ARCH_USES_SLAB_PAGE_STRUCT
+        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).
+For full documentation on the configuration files, see the file
+Documentation/kbuild/kconfig-language.txt.
