1. Add new ioctl(EXT4_IOC_DEFRAG) which returns the first physical
   block number of the specified file.  With this ioctl, a command
   gets the specified directory's.

Maybe I don't understand, but how is this different from the long-time
FIBMAP ioctl?

I can use FIBMAP instead of my new ioctl.
You are right.  I should have used FIBMAP ioctl...

I have to get the physical block number of the specified directory.
But FIBMAP is available only for a regular file, not for a directory.
So I will use my new ioctl.
