UDT            : _REAL_NOTIFY_SYNC
Data           :   this+0x0, Member, Type: struct _FAST_MUTEX, FastMutex
UDT            :     _FAST_MUTEX

Data           :   this+0x20, Member, Type: unsigned long, OwningThread
Data           :   this+0x24, Member, Type: unsigned long, OwnerCount

It's just initializing a fast mutex and setting the owner to NULL and  
count to 0.
