=== V2: * Use 64K for the IO_BUFSIZE and use malloc() to allocate the memory for the buffer respect to Darrick's comments. * Use calloc() and memcmp() to check the sparse block as Darrick suggested. * Adjust the frame and remove a few un-needed code as Darrick suggested. === V1: * 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.
