[openib-general] Re: [PATCH] mthca: fix posting long work request lists

[Roland Dreier]

The issue in this case is that if you do

	void foo(void)
	{
		{
			int x[2];
			/* stuff */
		}
		{
			int x[2];
			/* other stuff */
		}
	}

then gcc allocates stack space for two copies of x even though they
can never both be in scope.  I think gcc 4.1 might be better in this
area but that's a little futuristic.

So it's better to declare x once at the top of the function.
