Matthew Ahrens 20f287855a zvol_write() can use dmu_tx_hold_write_by_dnode() ... We can improve the performance of writes to zvols by using dmu_tx_hold_write_by_dnode() instead of dmu_tx_hold_write(). This reduces lock contention on the first block of the dnode object, and also reduces the amount of CPU needed. The benefit will be highest with multi-threaded async writes (i.e. writes that don't call zil_commit()).
