Subject: [PATCH] kbuild: disable compile-test of kernel headers for now
Date: Fri, 19 Jul 2019 19:08:59 +0900	[thread overview]
Message-ID: <20190719100859.11227-1-yamada.masahiro@socionext.com> (raw)

This compile-test started from the strong belief that (almost) all
headers should be able to be compiled as a standalone unit, but this
requirement seems to be just annoying.

I believe compile-test of exported headers is good. On the other hand,
in-kernel headers are not necessarily supposed to be always compilable.
Actually, some headers are only included under a certain combination
of CONFIG options, and that is definitely fine.

This test is still causing false positive errors in randconfig.
Moreover, newly added headers are compile-tested by default, sometimes
they catch (not fatal) bugs, but often raise false positive errors to
end up with making people upset.

The merge window is closing shortly, so there is not much I can do.
Disable it for now, and take a pause to re-think whether we should
continue this or change the course.
