Bug was introduced by cset 1.1659.14.1. Before it server was silently ignoring that lock can't be acquired because it already acquired. This patch makes make_global_read_lock_block_commit() return without error if lock already acquired. mysql-test/t/flush_table.test: Test case for bug#11934 FLUSH TABLES WITH READ LOCK hangs client. mysql-test/r/flush_table.result: Test case for bug#11934 FLUSH TABLES WITH READ LOCK hangs client. sql/lock.cc: Fix bug #11934 Two sequential FLUSH TABLES WITH READ LOCK hangs client. Make make_global_read_lock_block_commit() return without error if lock already acquired.
