Description
When stride-RA hit case miss, we only reset normal sequential read-ahead window, but not reset the stride IO to avoid the overhead of re-detecting stride IO. While when the normal RA window is set to not insect with the stride-RA window, when we try to increase the stride-RA window length later, the presumption does not hold.
This patch resets the stride IO as well in this case.
