Levin" Date: Thu, 14 Sep 2017 11:04:18 +1000 Subject: [PATCH 01/16] uapi: fix linux/sysctl.h userspace compilation errors Include (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.
