https://git.shady.money/linux/atom?h=v5.32019-07-09T01:10:52Zkheaders: include only headers into kheaders_data.tar.xz2019-07-09T01:10:52ZMasahiro Yamadayamada.masahiro@socionext.com2019-07-01T00:58:44Zurn:sha1:7199ff7d74003b5aad1e6328bf6128cd8ceea735
Currently, kheaders_data.tar.xz contains some build scripts as well as
headers. None of them is needed in the header archive.
For ARCH=x86, this commit excludes the following from the archive:
arch/x86/include/asm/Kbuild
arch/x86/include/uapi/asm/Kbuild
include/asm-generic/Kbuild
include/config/auto.conf
include/config/kernel.release
include/config/tristate.conf
include/uapi/asm-generic/Kbuild
include/uapi/Kbuild
kernel/gen_kheaders.sh
This change is actually motivated for the planned header compile-testing
because it will generate more build artifacts, which should not be
included in the archive.

kheaders: remove meaningless -R option of 'ls'2019-07-09T01:10:52ZMasahiro Yamadayamada.masahiro@socionext.com2019-07-01T00:58:43Zurn:sha1:b60b7c2ea9b7f854d457fefd592c77f621a86580
The -R option of 'ls' is supposed to be used for directories.
-R, --recursive
list subdirectories recursively
Since 'find ... -type f' only matches to regular files, we do not
expect directories passed to the 'ls' command here.
Giving -R is harmless at least, but unneeded.

kheaders: Do not regenerate archive if config is not changed2019-05-24T18:16:01ZJoel Fernandes (Google)joel@joelfernandes.org2019-05-15T21:35:52Zurn:sha1:1457dc9ed8da871fbbc0a2ebdaed0405eeeed0cf
Linus reported an issue that doing an allmodconfig was causing the
kheaders archive to be regenerated even though the config is the same.
This patch fixes the issue by ignoring the config-related header files
for "knowing when to regenerate based on timestamps". Instead, if the
CONFIG_X_Y option really changes, then we there are the
include/config/X/Y.h which will already tells us "if a config really
changed". So we don't really need these files for regeneration detection
anyway, and ignoring them fixes Linus's issue.

kheaders: Move from proc to sysfs2019-05-24T18:16:01ZJoel Fernandes (Google)joel@joelfernandes.org2019-05-15T21:35:51Zurn:sha1:f7b101d33046a837c2aa4526cef28a3c785d7af2
The kheaders archive consisting of the kernel headers used for compiling
bpf programs is in /proc. However there is concern that moving it here
will make it permanent. Let us move it to /sys/kernel as discussed [1].
