3.5.7.17 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Bart Van Assche <bart.vanassche@xxxxxxxxx> commit 9e04d3804d3ac97d8c03a41d78d0f0674b5d01e1 upstream. Direct compare of jiffies related values does not work in the wrap around case. Replace it with time_is_after_jiffies().
