3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Stefan Haberland <stefan.haberland@xxxxxxxxxx> commit 020bf042e5b397479c1174081b935d0ff15d1a64 upstream. The channel checks the specified length and the provided amount of data for CCWs and provides an incorrect length error if the size does not match. Under z/VM with simulation activated the length may get changed. Having the suppress length indication bit set is stated as good CCW coding practice and avoids errors under z/VM.
