From 26099eb8ac855aa08e5e1a307affe42fe5f43859 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Mon, 28 Oct 2013 14:32:40 +0000 Subject: scripts: Add ksize.py and dirsize.py Fixes [YOCTO #5388] These scripts can be useful when working to reduce the size of the Linux kernel and the root filesystem. ksize.py displays the kernel build size by the built-in.o files. dirsize.py displays the various sizes of the components of the root directory.
