Missing branch predictor annotations for fake changes
|Percona Server||Status tracked in 5.6|
Some, but not all, were fixed in the recent performance work. The fact that they weren't fixed there probably means they are not the worst offenders, but it's a good idea to maintain consistency.
Findable by grepping for "fake_change". Notable occurrences (i.e. more likely to be on hotter than colder code paths):
- in sql_insert.cc;
- in lock0lock.cc.
