You could also ihave switched over now, and accpet that this only would be used in -next for a few months. Then at least you did not have to rememebr to change it again. Any way works for me, just a suggestion. Sam

So, we can squash fix-up to avoid 0day bot report. I attached two patches. 00001-FIXUP1.patch is a one-liner fixup. If you want to clean up your Makefile by yourself later, I will squash it. If you want to switch to the generic notation now, I will squash 0001-FIXUP2.patch. Either is OK for me. Thanks. Masahiro Yamada

Except I don't think your linux-kbuild.git baseline has the files you're patching below. The problem only exists at the merge of our trees, currently only linux-next, and not "for real" until the v5.3 merge window. So I think the sane option is to patch it up in our tree. I want to use our local hack until we can get the backmerge from v5.3-rc1, because it's 7-8 weeks away, and I want to retain our own pre-merge build test coverage until then rather than relying on 0day post-merge testing on linux-next.

I do not understand. This is a _real_ problem since drivers/gpu/drm/i915/Makefile.header-test exists in Linus' tree. The 0-day bot reported the build error against my tree, so I must fix it in my tree. > I want to use our local hack until we can get the backmerge from > v5.3-rc1, because it's 7-8 weeks away, and I want to retain our own > pre-merge build test coverage until then rather than relying on 0day > post-merge testing on linux-next. Neither of my patches breaks your test coverage. CONFIG_DRM_I915_WERROR still works in linux-next too. What am I missing? Thanks. Masahiro Yamada

Apologies, my bad. I completely failed to realize Makefile.header-test already hit Linus' tree. *facepalm* You're totally right, it needs to be fixed in your tree. For that, I think the best option is your fixup patch #2. (Now that header-test-y is behind CONFIG_HEADER_TEST=y, I don't think this really requires CONFIG_DRM_I915_WERROR=y anymore, but no big deal either way.) We do have two more instances in -next that are not in Linus' tree, so we'll need to fix those locally anyway. Part of the confusion.
