From 5fd27fc84998c6683728353f57dc7c6000e5b4c3 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Thu, 11 Apr 2013 12:17:53 +0000 Subject: [PATCH] fs/ext2: add support for ext2 rev0 and rev1 Some bootloaders have a buggy ext2 support, and require ext2 rev1 instead of the traditional ext2 rev0 that genext2fs produces. tune2fs accepts only one '-O list' at a time, so we need to construct a list of -O options.
