Interlocked.CompareExchange using GreaterThan or LessThan instead of equality

Question

The System.Threading.Interlocked object allows for Addition (subtraction) and comparison as an atomic operation. It seems that a CompareExchange that just does

Answer 1

What do you think about this implementation:

// this is a Interlocked.ExchangeIfGreaterThan implementation
private static void ExchangeIfGreaterThan(ref long location, long value)
{
    // read
    long current = Interlocked.Read(ref location);
    // compare
    while (current < value)
    {
        // set
        var previous = Interlocked.CompareExchange(ref location, value, current);
        // if another thread has set a greater value, we can break
        // or if previous value is current value, then no other thread has it changed in between
        if (previous == current || previous >= value) // note: most commmon case first
            break;
        // for all other cases, we need another run (read value, compare, set)
        current = Interlocked.Read(ref location);
    }
