Configure read-ahead of dm-verity devices. For the /system and /vendor partitions, read-ahead is configured at 2048kB during boot and 128kB afterwards. Until we have clear data that 2048kB is better, explicitly stick to 128kB. We don't need to set read-ahead on the loop devices, because we will use Direct I/O on them, which disables read-ahead. Bug: 117823094 Test: cat /sys/block/dm-2/queue/read_ahead_kb says 128 Change-Id: I4a5a2ae57f0ff60bbdb6f7717b5799546fe0eb30
