I'm not sure what you mean by "via" VFS, but most HSM implementations on linux require extra interfaces and special support in the filesystem (XDSM or propriatary). The only exceptions I know are openXDSM which was intended to be a generic interface in the VFS-layer (but we never got time to implement it) and a implementation based on stackable filesystem. I don't know if the later is actually in use anywere, or if it is abandoned. -- Ragnar Kj?rstad Zet.no - 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/
