From 7b1e1a2202a492d492d4fb8ef25a5e648daed774 Mon Sep 17 00:00:00 2001 From: Juan Quintela Date: Mon, 17 Apr 2017 20:26:27 +0200 Subject: [PATCH] migration: Export ram.c functions in its own file All functions are internal except for ram_mig_init(). Create migration/misc.h for this kind of functions.
