Description

In practice, this means that replicated pgs will scan their log on the first operations after boot needlessly. EC pgs will tend to send an unnecessary transaction with the first operation after boot.

Hi sam:

"EC pgs will tend to send an unnecessary transaction with the first operation after boot."

This unnecessary transaction is supposed to be very big if the log tail is far away from the last rollback_info_trimmed_to(before reboot), right?
