In current zil_commit() process, transaction lwb_tx is assigned in zil_lwb_write_issue(), and is committed in zil_lwb_flush_vdevs_done(). Thus, during lwb write out process, the txg is held in open or quiesing state, until zil_lwb_flush_vdevs_done() is called. If the zil's zio latency is high, it will cause txg_sync_thread() to starve. The goal here is to defer waiting for zil_lwb_flush_vdevs_done to the 'syncing' txg state. That is, in zil_sync(). In this patch, it achieves the goal without holding transaction. A new function zil_lwb_flush_wait_all() is introduced. It waits for the completion of all the zil_lwb_flush_vdevs_done() by given txg.
