Description:
Manual page on instruments naming for PERFORMANCE_SCHEMA (http://dev.mysql.com/doc/refman/5.6/en/performance-schema-instrument-naming.html) says:
"statement/com: An instrumented command operation. These have names corresponding to COM_xxx operations (see the mysql_com.h header file and sql/sql_parse.cc. For example, the statement/com/Connect and statement/com/Fetch instruments correspond to the COM_CONNECT and COM_FETCH commands."
I think COM_FETCH is not a good example, as I can not find it neither in mysql_com.h header nor in recent source code any more. Maybe you meant something like COM_STMT_FETCH?

COM_STMT_FETCH command.

Suggested fix:
Fix that manual page to mention COM_* commands that are really supported in current MySQL 5.6.
