      treewide: Convert del_timer*() to timer_shutdown*() · 292a089d
      Steven Rostedt (Google) authored
      Due to several bugs caused by timers being re-armed after they are
      shutdown and just before they are freed, a new state of timers was added
      called "shutdown".  After a timer is set to this state, then it can no
      longer be re-armed.
      
      The following script was run to find all the trivial locations where
      del_timer() or del_timer_sync() is called in the same function that the
      object holding the timer is freed.  It also ignores any locations where
      the timer->function is modified between the del_timer*() and the free(),
      as that is not considered a "trivial" case.
      
      This was created by using a coccinelle script and the following
      commands:
      
          $ cat timer.cocci
          @@
          expression ptr, slab;
          identifier timer, rfield;
          @@
          (
          -       del_timer(&ptr->timer);
          +       timer_shutdown(&ptr->timer);
          |
          -       del_timer_sync(&ptr->timer);
          +       timer_shutdown_sync(&ptr->timer);
          )
            ... when strict
                when != ptr->timer
          (
                  kfree_rcu(ptr, rfield);
          |
                  kmem_cache_free(slab, ptr);
          |
                  kfree(ptr);
          )
      
          $ spatch timer.cocci . > /tmp/t.patch
          $ patch -p1 < /tmp/t.patch
