From 3286a4d6aa2707e9dcdcb26e7c391bd7a07eddad Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Tue, 4 Jul 2017 00:50:59 +0200 Subject: [PATCH] fs/ext2: allow reserving zero block for root The previous default, zero, just meant "use the default value of the filesystem generator", which happened to be 5% (the traditional value for all ext-creating tools we've ever seen). So, change the new default accordingly to 5%. Signed-off-by: "Yann E.
