Bug Description
It may be not obvious why it is needed, but it is for integration Percona Server with Galera replication.
When we propagate new node we want node to start in "warm" state, and for this - preload buffer pool dump from disk before
InnoDB reports to MySQL that it started.
Looking into source code - it is just two-lines fix.
I propose to make special startup option i.e. --enable-
