![]() The code block surrounded by 'if' ... 'endif' is reduced into if_stmt, which is accepted in the 'choice' context. Therefore, you can write any statements within a choice block by wrapping 'if y' ... 'end'. For example, you can create a menu inside a choice, like follows: ---------------->8---------------- choice prompt "choice" config A bool "A" config B bool "B" if y menu "strange menu" config C bool "C" endmenu endif endchoice ---------------->8---------------- I want to change such a weird structure into a syntax error. In fact, the USB gadget Kconfig had used nested 'choice' for no good reason until commit |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
