[v1] kbuild: support building external modules in a separate build directory

[PATCH 02/23] kbuild: doc: remove description about grepping CONFIG options

Posted by Masahiro Yamada 2 months, 1 week ago

This description was added 20 years ago [1]. It does not convey any
useful information except for a feeling of nostalgia.

-	External modules have traditionally used "grep" to check for
-	specific `CONFIG_` settings directly in .config. This usage is
-	broken. As introduced before, external modules should use
-	kbuild for building and can therefore use the same methods as
-	in-tree modules when testing for `CONFIG_` definitions.
