[PATCH] kbuild: pacman-pkg: package unstripped vDSO libraries

[PATCH] kbuild: pacman-pkg: package unstripped vDSO libraries

[Thomas Weißschuh]

The unstripped vDSO files are useful for debugging.
They are provided in the upstream 'linux-headers' package.

Also package them as part of 'make pacman-pkg'.
Make them part of the '-debug' package, as they fit there best.
This differs from the upstream package as that has no '-debug' variant.

In my opinion the same would be useful for debian and rpm packages.
Maybe we should have install-extmod-debug, similar to
install-extmod-build, to centralize these.

Seems reasonable to me.

Applied to kbuild/linux.git (kbuild-next-unstable), thanks!

[1/1] kbuild: pacman-pkg: package unstripped vDSO libraries
      https://git.kernel.org/kbuild/c/165e86c2

Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped,
reverted or modified (e.g. trailers). Patches applied to the
kbuild-next-unstable branch are accepted pending wider testing in
linux-next and any post-commit review; they will generally be moved
to the kbuild-next branch in about a week if no issues are found.

Best regards,

I can't find this patch anywhere (mainline, linux-next, kbuild branches),
but there are no further comments on the mailing lists.

Was the patch dropped or did it get lost?

Best regards,
Viktor

thanks for spotting!  You're right, it got lost.  I have that commit still in my
local git tree but w/o any branch referencing it.  I'm sorry.


Nathan, can you please pick this one up for v7.2?


Kind regards,
Nicolas
