Renamed it so that it doesn't say 'hack', took out the loop to allocate memory. Tasks left for someone more familiar with the NFS code are: - making it use one of the pages already allocated for the response. - giving it a hint about how many dirents to read into the buffer. -- David Woodhouse Open Source Technology Centre David.Woodhouse@xxxxxxxxx Intel Corporation -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
