-debugfs: properly set up extent header in do_write
-
-do_write doesn't fully set up the first extent header on a new
-inode, so if we write a 0-length file, and don't write any data
-to the new file, we end up creating something that looks corrupt
-to kernelspace:
-
-EXT4-fs error (device loop0): ext4_ext_check_inode:464: inode #12: comm ls: bad header/extent: invalid magic - magic 0, entries 0, max 0(0), depth 0(0)
-
-Do something similar to ext4_ext_tree_init() here, and
-fill out the first extent header upon creation to avoid this.

-debugfs.c: do sparse copy when src is a sparse file
-
-Let debugfs do sparse copy when src is a sparse file, just like
-"cp --sparse=auto"
-
-* For the:
- #define IO_BUFSIZE 64*1024
- this is a suggested value from gnu coreutils:
- http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=blob;f=src/ioblksize.h;h=1ae93255e7d0ccf0855208c7ae5888209997bf16;hb=HEAD
-
-* Use malloc() to allocate memory for the buffer since put 64K (or
- more) on the stack seems not a good idea.

-debugfs.c: the max length of debugfs argument is too short
-
-The max length of debugfs argument is 256 which is too short, the
-arguments are two paths, the PATH_MAX is 4096 according to
-/usr/include/linux/limits.h, so use BUFSIZ (which is 8192 on Linux
-systems), that's also what the ss library uses.
