From: Wei Yongjun <redacted> Use setup_timer() instead of init_timer(), being the preferred/standard way to set a timer up. Also, quoting the mod_timer() function comment: -> mod_timer() is a more efficient way to update the expire field of an active timer (if the timer is inactive it will be activated). Use setup_timer and mod_timer to setup and arm a timer, to make the code cleaner and easier to read.
