Message-ID: <1374200257-2873-1-git-send-email-liezhi.yang@windriver.com> Date: Fri, 19 Jul 2013 10:17:35 +0800 From: Robert Yang <liezhi.yang@...driver.com> To: <tytso@....edu>, <dvhart@...ux.intel.com> CC: <linux-ext4@...r.kernel.org> Subject: [PATCH 0/2] e2fsprogs/debugfs: do sparse copy when src is a sparse file * There are two patches, one is used for fixing the max length of the argument, the other one is for sparsing copy when src is a sparse file. * BTW., we are trying to use the debugfs to create an ext2/ext3/ext4 image based on a given directory or file, which is similar to genext2fs, please vist here for the script you are interested in it: https://gist.github.com/robertlinux/6034499 It is an external shell script at the moment, the performance is not good, so we are going to: - Integrate this function into mke2fs in C language. - Add a [-d <directory>] option to specify the initial directory in mke2fs I'm not sure whether such a patch is acceptable or not, please feel free to give your comments.
