OK, after thinking about this some more, it seems clear that ReiserFS
should *automatically* "unpack" files which have the Linux blockmap ioctl
made upon them.

Having to do filesystem-specific hacks when the filesystem already has
a clue about what's happening is just broken behavior.

I'm going to talk to the Reiser folks to see about this, probably tonight/
tomorrow sometime.

I think I'll also propose this on the Linux-Kernel email list as
the "defined" behavior of the FIBMAP ioctl, as well.
