In most cases dmu_sync() works with dirty records directly and does not need actual data. The only exception is dmu_sync_late_arrival(). To save some CPU time use dmu_buf_hold_noread*() in z*_get_data() and explicitly call dbuf_read() in dmu_sync_late_arrival(). There is also a chance that by that time TXG will already be synced and we won't have to do it at all.
