3.6.11.7-rc1 stable review patch. If anyone has any objections, please let me know. ------------------ From: Bart Van Assche [ Upstream commit 9e04d3804d3ac97d8c03a41d78d0f0674b5d01e1 ] Direct compare of jiffies related values does not work in the wrap around case. Replace it with time_is_after_jiffies().
