CONFIG_IKHEADERS has a reproducibility issue because the contents of kernel/kheaders_data.tar.xz can vary depending on how you build the kernel. If you build the kernel with CONFIG_IKHEADERS enabled from a pristine state, the tarball does not include include/generated/utsversion.h. $ make -s mrproper $ make -s defconfig $ scripts/config -e CONFIG_IKHEADERS $ make -s $ tar Jtf kernel/kheaders_data.tar.xz | grep utsversion However, if you build the kernel with CONFIG_IKHEADERS disabled first and then enable it later, the tarball does include include/generated/utsversion.h. $ make -s mrproper $ make -s defconfig $ make -s $ scripts/config -e CONFIG_IKHEADERS $ make -s $ tar Jtf kernel/kheaders_data.tar.xz | grep utsversion ./include/generated/utsversion.h It is not predictable whether a stale include/generated/utsversion.h remains when kheaders_data.tar.xz is generated. For better reproducibility, include/generated/utsversions.h should always be omitted. It is not necessary for the kheaders anyway. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
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 reStructuredText 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.
