Let us try to avoid code bloat for the common case that performance_schema is disabled at runtime, and use ATTRIBUTE_NOINLINE member functions for instrumented latch acquisition. Also, let us distinguish lock waits from non-contended lock requests by using write_lock,read_lock for the requests that lead to waits, and try_write_lock,try_read_lock for the wait-free lock acquisitions. Actual 'try' operations are not being instrumented at all. |
