func CreateLocks ¶

func CreateLocks() []*LockEntry

CreateLocks returns an array so that the locks can be itterated over in order.

This is only threadsafe if a process is using a single lock, or iterating over the entire lock slice in order. Using a consistant order avoids deadlocks because you can never have the following:

Lock A, Lock B Lock B, Lock A

Where process 1 is now deadlocked trying to lock B, and process 2 deadlocked trying to lock A
