Subject: uapi: fix linux/rds.h userspace compilation error

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;
