Reduce readahead from 512KiB to 128KiB to reduce thrashing when we have a lot of apps running. Bug: 110908295 Bug: 80426378 Test: manual - device boots Test: manual - check app launch does not take long Test: cts-tradefed.sh run cts -m CtsCameraTestCases Change-Id: I59c1f2f8a6fbb5e0d956ba07a40a2bfac3b61481
