Add a routine that dumps memory-related values of a socket. It's made as an array to make it possible to add more stuff here later without breaking compatibility. Since v1: The SK_MEMINFO_ constants are in userspace visible part of sock_diag.h, the rest is under __KERNEL__. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S.
