- Split dmu_prefetch_dnode() from dmu_prefetch() into a separate function. It is quite inconvenient to read the code where len = 0 means dnode prefetch instead indirect/data prefetch. One function doing both has no benefits, since the code paths are independent. - Improve dmu_prefetch() handling of long block ranges. Instead of limiting L0 data length to prefetch for to dmu_prefetch_max, make dmu_prefetch_max limit the actual amount of prefetch at the specified level, and, if there is more, prefetch all the rest at higher indirection level. It should improve random access times within the prefetched range of any length, reducing importance of specific dmu_prefetch_max value.
