From a2d133b1d465016d0d97560b11f54ba0ace56d3e Mon Sep 17 00:00:00 2001 From: Josh Hunt Date: Mon, 20 Mar 2017 15:22:03 -0400 Subject: sock: introduce SO_MEMINFO getsockopt Allows reading of SK_MEMINFO_VARS via socket option. This way an application can get all meminfo related information in single socket option call instead of multiple calls. Adds helper function, sk_get_meminfo(), and uses that for both getsockopt and sock_diag_put_meminfo(). Suggested by Eric Dumazet.
