event-tap controls when to start FT transaction, and provides proxy
functions to called from net/block devices. While FT transaction, it
queues up net/block requests, and flush them when the transaction gets

event-tap record block and io wirte events, and replay these on
the other side, so block_save_live is useless during the latter ft
phase, right? if so, I think it need to process the following code in
block_save_live function:
