Subject: [PATCH 5/7] checkpatch: warn if <asm/export.h> is included
Date: Sat, 11 Jun 2022 03:32:34 +0900 [thread overview]
Message-ID: <20220610183236.1272216-6-masahiroy@kernel.org> (raw)
In-Reply-To: <20220610183236.1272216-1-masahiroy@kernel.org>
With the previous refactoring,
- <asm/export.h> is a wrapper of <asm-generic/export.h>
- <asm-generic/export.h> is a wrapper of <linux/export.h>
My hope is to replace
#include <asm/export.h> --> #include <linux/export.h>
for all *.S files.
For now, adding a warning in the checkpatch.
