cancel_delayed_work() has to use del_timer_sync() to guarantee the timer function is not running after return. But most users doesn't actually need this, and del_timer_sync() has problems: it is not useable from interrupt, and it depends on every lock which could be taken from irq. Introduce __cancel_delayed_work() which calls del_timer() instead. The immediate reason for this patch is http://bugzilla.kernel.org/show_bug.cgi?id=13757 but hopefully this helper makes sense anyway. As for 13757 bug, actually we need requeue_delayed_work(), but its semantics are not yet clear. Merge this patch early to resolves cross-tree interdependencies between input and infiniband.
