Subject: [PATCH] uapi: fix linux/sysctl.h userspace compilation errors
Date: Thu, 23 Feb 2017 02:06:52 +0300 [thread overview]
Message-ID: <20170222230652.GA14373@altlinux.org> (raw)
Include <stddef.h> (guarded by #ifndef __KERNEL__) to fix the following
linux/sysctl.h userspace compilation errors:
/usr/include/linux/sysctl.h:38:2: error: unknown type name 'size_t'
size_t *oldlenp;
/usr/include/linux/sysctl.h:40:2: error: unknown type name 'size_t'
size_t newlen;
This also fixes userspace compilation of uapi headers that include
linux/sysctl.h, e.g. linux/netfilter.h.
