Johannes Berg d65197ad52 um: Fix time-travel=inf-cpu with xor/raid6 ... Today, I erroneously built a time-travel configuration with btrfs enabled, and noticed it cannot boot in time-travel=inf-cpu mode, both xor and raid6 speed measurement gets stuck. For xor, work around it by picking the first algorithm if inf-cpu mode is enabled. For raid6, I didn't find such a workaround, so disallow enabling time-travel mode if RAID6_PQ_BENCHMARK is enabled. With this, and RAID6_PQ_BENCHMARK disabled, I can boot a kernel that has btrfs enabled in time-travel=inf-cpu mode.
