Subject: [PATCH] kbuild: fix mismatch between .version and include/generated/compile.h
Date: Tue, 11 Feb 2020 05:06:34 +0900 [thread overview]
Message-ID: <20200210200634.950-1-masahiroy@kernel.org> (raw)
Since commit 56d589361572 ("kbuild: do not create orphan built-in.a or
obj-y objects"), scripts/link-vmlinux.sh does nothing when descending
into init/.
Once the version number becomes out of sync between .version and
include/generated/compile.h, it is not self-healing.
[How to reproduce]
$ echo 100 > .version
$ make
You will see the number in the .version is always bigger than that in
compile.h by one. After this, every time you run 'make', the vmlinux is
re-linked even when none of source files is updated.
Fixes: 56d589361572 ("kbuild: do not create orphan built-in.a or obj-y objects")
