revno: 2617.22.5
committer: Konstantin Osipov <kostja@sun.com>
branch nick: mysql-6.0-runtime
timestamp: Tue 2009-01-27 05:08:48 +0300
message:
  Remove non-prefixed use of HASH.
  Always use my_hash_init(), my_hash_inited(), my_hash_search(),
  my_hash_element(), my_hash_delete(), my_hash_free() rather
  than non-prefixed counterparts (hash_init(), etc).
  Remove the backward-compatible defines.
