This path doesnot exist. But in any case, i think the patch is wrong. wait_event_interruptible() is executed when most_get_mbo() returns NULL. so if you do mbo == most_get_mbo() it will immediately come out of sleep as the condition is true. I think here the intention was to sleep as long as most_get_mbo() returns NULL. And when it returns a valid pointer it is saved in mbo variable so that it can be used later in copy_from_user(). regards sudip _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
