+Subject: [PATCH] malloc: Fix missing accounting of top chunk in malloc_info
+ [BZ #24026]
+
+Fixes `<total type="rest" size="..."> incorrectly showing as 0 most
+of the time.
+
+The rest value being wrong is significant because to compute the
+actual amount of memory handed out via malloc, the user must subtract
+it from <system type="current" size="...">. That result being wrong
+makes investigating memory fragmentation issues like
+<https://bugzilla.redhat.com/show_bug.cgi?id=843478> close to
+impossible.
