I have a need for a very simple f/s that supports only one file on a raw
device, starting from the beginning of the device and growing until possibly
its end. The reason for this simple f/s is to minimize the overhead for
certain applications that don't need more than one large file, but cannot
use a raw device directly (i.e., they expect a f/s interface). Do you know
of any f/s that does that for Linux?
Thanks,
Erez.

iirc there was one long ago from Miquel van Smoorenburg for 2.4 (or maybe
2.2 i don't remember). But if you want it for 2.6 it would be probably
easier to just rewrite it.

We actually have a filesystem that represents blockdevices as single big file
in fs/block_dev.c. It's just not mountable.
