mutex_wait_snapshot_t Struct Reference

For mutex wait snapshot, this is the live record that ties mutex_key, thread_key, since_ns, cycle together. The owning code creates it, updates it while work is active, and releases its handles and pointed-to storage before freeing the record. More...

Detailed Description

For mutex wait snapshot, this is the live record that ties mutex_key, thread_key, since_ns, cycle together. The owning code creates it, updates it while work is active, and releases its handles and pointed-to storage before freeing the record.
