This patch hooks up swap-scheduling function with vblank-extrapolation function. Rather than waiting for fixed time, we calculate exactly how much we should wait and what we should update target_msc to using radeon_dri2_extrapolate_msc_delay helper function and schedule the swap completion using DIX's timer facility.
