Subject[PATCH 4.9 58/72] uapi: fix linux/rds.h userspace compilation error
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Dmitry V. Levin" <ldv@altlinux.org>


[ Upstream commit 1786dbf3702e33ce3afd2d3dbe630bd04b1d2e58 ]

On the kernel side, sockaddr_storage is #define'd to
__kernel_sockaddr_storage. Replacing struct sockaddr_storage with
struct __kernel_sockaddr_storage defined by <linux/socket.h> fixes
the following linux/rds.h userspace compilation error:

/usr/include/linux/rds.h:226:26: error: field 'dest_addr' has incomplete type
struct sockaddr_storage dest_addr;
