  sql_update.cc:
    Fix Bug #3300 in the case submitted by the user: an update of the PRIMARY KEY; we do
this by releasing the row lock on rows that do not match the WHERE condition; NOTE that
there are several other places in MySQL code where we still have to add a call on
unlock_row()
  lock0lock.c:
