Yes, of cousre. > Anyways I don't see any visible EXPORT_SYMBOL in reiser4. Yes, there's no module infrastructure there. These "plugins" need to be linked at compile time. Some plugins need to be anyway since the the filesystem is useless without them.

The name is probably at bit misleading. But assuming the compression "plugin" whould be dynamically loadable at some later point it would be a plugin then?
