* Qualcomm decided to increase the read-ahead value to 512KiB [1]. * This value resulted in frequent cases where read-ahead would be waiting for new I/O requests and thus ending up being synchronous rather than asynchronous. * As result, the main goal of Qualcomm's patch [1] which is to increase throughput ends up in a regression where read throughput is significantly lower than it ever would be with the recommended [2] read-ahead value. * This patch uses our existing loop in ramdisk to set the read-ahead value to 128KiB.
