Raw Blame History

This is a partial recreation of this upstream commit, restricted to
the malloc_info function:
commit 6c8dbf00f536d78b1937b5af6f57be47fd376344
Author: Ondřej Bílka <neleai@seznam.cz>
Date: Thu Jan 2 09:38:18 2014 +0100
Reformat malloc to gnu style.
It is not an exact copy because glibc-rh1103856.patch backported
commit 4d653a59ffeae0f46f76a40230e2cfa9587b7e7e ("Add mmap usage in
malloc_info output"), which came after the reformatting upstream.
