ZFS prefetch is currently governed by the zfs_prefetch_disable tunable. However, this is a module-wide settings - if a specific dataset benefits from prefetch, while others have issue with it, an optimal solution does not exists. This commit introduce the "prefetch" tri-state property, which enable granular control (at dataset/volume level) for prefetching. This patch does not remove the zfs_prefetch_disable, which remains a system-wide switch for enable/disable prefetch. However, to avoid duplication, it would be preferable to deprecate and then remove the module tunable.
