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.
if CONFIG_EXPERIMENTAL
tristate CONFIG_BOOM
default n
config AUDIT
bool "Auditing support"
depends on NET
help
Apply nitroglycerine inside the keyboard (DANGEROUS)
bool CONFIG_CHEER
depends on CONFIG_BOOM
default y
help
Output nice messages when you explode
endif
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.
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).
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
...

Documentation/kbuild/kconfig-language.txt.
