Description:
The HASH Partitioning page contains the following:

"You may use any function or other expression for expr that is valid in MySQL, so long as it returns a non-constant, non-random integer value."

which isn't true anymore - only a limited set of functions are permitted, at the moment anyway.

How to repeat:
http://dev.mysql.com/doc/refman/5.1/en/partitioning-hash.html

Suggested fix:
Edit the sentence to refer to the limitations at http://dev.mysql.com/doc/refman/5.1/en/partitioning-limitations.html
