It was introduced in 5.1.44, and counts the number of times my_sync()
was called. It's basically the number of times the server had to force
data to disk. It covers the binary log, frm creation (if these
operations are configured to sync), and some storage engines (Archive,
CSV, Aria), but not InnoDB or XtraDB.
