I don't think so, e.g. many filesystems store interesting information (such as directories, for example) in files they do read and write into and what's more, they usually do this through something quite similar to the memmap approach. And so that is also my advice, have a look at how for example minix works with directories and do something similar. HTH Martin Jambor -- Kernelnewbies: Help each other learn about the Linux kernel.
