From 5d2e5f274f9e9a06fb934dd45260e2616a9992e6 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Fri, 30 Dec 2011 00:53:13 +0000 Subject: sock_diag: Introduce the meminfo nla core (v2) 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 Signed-off-by: David S.
