I'm not sure what you're doing here, but a viable work-around for now might be to use nfsv2 mounts, something like mount -o vers=2 ... or to keep v3 and disable readdirplus doing something like: mount -o vers=3,nordirplus ... The later I didn't test but was suggested on #linuxfs. - 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/
