treewide: Convert del_timer() to timer_shutdown()

2022-12-25T21:38:09Z

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 Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) Acked-by: Pavel Machek [ LED ] Acked-by: Kalle Valo [ wireless ] Acked-by: Paolo Abeni [ networking ] Signed-off-by: Linus Torvalds

Input: tegra-kbc - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2022-12-07T21:28:20Z

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the ifdef guards. Signed-off-by: Jonathan Cameron Link: https://lore.kernel.org/r/20221204180841.2211588-27-jic23@kernel.org Signed-off-by: Dmitry Torokhov
