It's the same pattern and I did go back to see if I had broken other places but, obviously, I missed this one. It's annoying enough that I'm trying to figure out a better way to do this in general.. A contiguous iterator of sorts. I will add this to my maple tree work list [1]. [1] http://lists.infradead.org/pipermail/maple-tree/2023-July/002683.html Thanks, Liam
