Bug#24988 FLUSH PRIVILEGES causes brief unavailability
- A race condition caused brief unavailablility when trying to acccess a table. - The unprotected variable 'grant_option' wasn't intended to alternate during normal execution. Variable initialization moved to grant_init a lines responsible for the alternation are removed. sql/mysqld.cc: - Added documentation to describe grant_option flag. sql/sql_acl.cc: - This patch removes lines which causes grant_option to alternate and moves variable initialization to the grant_init()-function.
