Let me sort this out: If it can't be done POSIXly to a directory, it can't be done in Reiser4 to a file (which really is a directory too). So there can be exactly _one_ hard link to a file.

I'd suspect if it can be made to work, it will have _huge_ overhead, so much that it is useless. I'd love to be proven wrong, but I won't hold my breath. -- Dr. Horst H. von Brand User #22616 counter.li.org Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
