Message-ID: <1388135345-2006-9-git-send-email-liezhi.yang@windriver.com> Date: Fri, 27 Dec 2013 04:09:02 -0500 From: Robert Yang <liezhi.yang@...driver.com> To: <tytso@....edu>, <dvhart@...ux.intel.com> CC: <linux-ext4@...r.kernel.org> Subject: [PATCH V3 08/11] mke2fs.c: add an option: -d root-directory This option is used for adding the files from a given directory (the root-directory) to the filesystem, it is similiar to genext2fs, but genext2fs doesn't fully support ext4.
