Date:   Fri, 26 Jun 2020 10:07:10 +0200
From:   Christoph Hellwig <hch@....de>
To:     Yoshinori Sato <ysato@...rs.sourceforge.jp>,
        Rich Felker <dalias@...c.org>
Cc:     linux-sh@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH 03/10] sh: remove __KERNEL__ ifdefs from non-UAPI headers

There is no point in having __KERNEL__ ifdefs in headers not exported to
userspace.
