From mboxrd@z Thu Jan 1 00:00:00 1970 From: Samuel Martin Date: Mon, 3 Jul 2017 17:51:50 +0200 Subject: [Buildroot] [PATCH v2 2/6] fs/ext2: allow reserving zero block for root In-Reply-To: <20170703155154.24104-1-s.martin49@gmail.com> References: <20170703155154.24104-1-s.martin49@gmail.com> Message-ID: <20170703155154.24104-3-s.martin49@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net From: "Yann E. MORIN" 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.
