From 8c7c6eb1675b327387a24bc05ac98dfc890f8073 Mon Sep 17 00:00:00 2001 From: Andreas Dilger Date: Wed, 9 Jan 2008 20:59:47 +0100 Subject: [PATCH] mke2fs: Make lost+found always have at least 2 blocks Make sure lost+found has always at least 2 disk blocks. This will provide at least elementary test that we have not screwed-up support for 64KB blocks since the second directory block will be empty.
