Linux kernel source tree
61277981dd
The comment above the silentoldconfig invocation is outdated. 'make oldconfig' updates just .config and doesn't touch the include/config/ tree. This came up in https://lkml.org/lkml/2018/2/12/415. While fixing the comment, make it more informative by explaining the purpose of the unfortunately named silentoldconfig. I can't make sense of the comment re. auto.conf.cmd and a cleaned tree. include/config/auto.conf and include/config/auto.conf.cmd are both created simultaneously by silentoldconfig (in scripts/kconfig/confdata.c, by conf_write_autoconf()), and nothing seems to remove auto.conf.cmd that wouldn't remove auto.conf. Remove that part of the comment rather than blindly copying it. It might be a leftover from an older way of doing things. The include/config/auto.conf.cmd prerequisite might be there to ensure that silentoldconfig gets rerun if conf_write_autoconf() fails between writing out auto.conf.cmd and auto.conf (a comment in the function indicates that auto.conf is deliberately written out last to mark completion of the operation). It seems the Makefile dependency between include/config/auto.conf and .config would already take care of that though, since include/config/auto.conf would still be out of date re. .config if the operation fails. Cop out and leave the prerequisite in for now. Signed-off-by: Ulf Magnusson <ulfalizer@gmail.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
