This script is originally from Darren Hart, it will be used for creating
the ext* filesystem from a given directory, which will replace the
genext2fs in image_types.bbclass at the moment, we may use the mke2fs to
replace this script again when it has the initial directory support.
Changes of the script:
* Rename it from mkdebugfs.sh to populate-extfs.sh
* Add a simple usage
* Add checking for the number of the parameters
* Add the "regular empty file" and "fifo" file type
* Set mode, uid and gid for the file
* Save the command lines to a file and batch run them
* Change the error message
* Improve the performance
* Add the support for hardlink

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.

We only read the cache when:
bufsize == sizeof(struct ext2_inode)
then we should only update the cache in the same condition, otherwise
there would be errors, for example:
cache[0]: cached ino 14 when bufsize = 128 by ext2fs_write_inode_full()
cache[1]: cached ino 14 when bufsize = 156 by ext2fs_read_inode_full()
Then update the cache:
cache[0]: cached ino 15 when bufsize = 156 by ext2fs_read_inode_full()
Then the ino 14 would hit the cache[1] when bufsize = 128 (but it was
cached by bufsize = 156), so there would be errors.

Let debugfs do sparse copy when src is a sparse file, just like
"cp --sparse=auto"

merged atm.

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.

There were darwin8/darwin9 overrides spinkled in the code from times gone
by. Lets settle on the darwin override and remove the others since its pointless
duplication. We always inject darwin into OVERRIDES if needed in the darwin8/9
cases.
