If we want to warn about such failures, we should add the warning consistently across the code. We may also want to handle decrypt failures by encrypting the page again to avoid leaking it. I will work on that as a tree-wide change in a separate patch.
IMHO the WARN should be inside set_memory_encrypted(), and maybe it should be a BUG_ON... "free" functions shouldn't fail, and returning the memory back to normal is a "free" operation. Jason
