From 883179b493d610fe8b4fb8f853dbd37e25903b33 Mon Sep 17 00:00:00 2001 From: Anatoly Burakov Date: Wed, 11 Apr 2018 13:29:43 +0100 Subject: [PATCH] malloc: make free return resulting element This will be needed because we need to know how big is the new empty space, to check whether we can free some pages as a result.
