Subject: [PATCH 4.4 09/19] uapi: move constants from <linux/kernel.h> to <linux/const.h>
Date: Thu, 7 Jan 2021 15:16:34 +0100 [thread overview]
Message-ID: <20210107140828.015078407@linuxfoundation.org> (raw)
In-Reply-To: <20210107140827.584658199@linuxfoundation.org>
From: Petr Vorel <petr.vorel@gmail.com>
commit a85cbe6159ffc973e5702f70a3bd5185f8f3c38d upstream.
and include <linux/const.h> in UAPI headers instead of <linux/kernel.h>.
The reason is to avoid indirect <linux/sysinfo.h> include when using
some network headers: <linux/netlink.h> or others -> <linux/kernel.h>
-> <linux/sysinfo.h>.
This indirect include causes on MUSL redefinition of struct sysinfo when
included both <sys/sysinfo.h> and some of UAPI headers:
