From acf7a951894a1b445ff61e945e32c989892f476f Mon Sep 17 00:00:00 2001 From: Brian Geffon Date: Tue, 9 Oct 2018 09:51:01 -0700 Subject: Add memunit to sysinfo(2). Also properly add padding after Procs in the linux.Sysinfo structure. This will be implicitly padded to 64bits so we need to do the same.
