Subject: [PATCH 5.10 22/63] uapi: move constants from <linux/kernel.h> to <linux/const.h>
Date: Mon, 4 Jan 2021 16:57:15 +0100 [thread overview]
Message-ID: <20210104155709.897542552@linuxfoundation.org> (raw)
In-Reply-To: <20210104155708.800470590@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:
