kthread: mark timer used by delayed kthread works as IRQ safe
The timer used by delayed kthread works are IRQ safe because the used kthread_delayed_work_timer_fn() is IRQ safe. It is properly marked when initialized by KTHREAD_DELAYED_WORK_INIT(). But TIMER_IRQSAFE flag is missing when initialized by kthread_init_delayed_work(). The missing flag might trigger invalid warning from del_timer_sync() when kthread_mod_delayed_work() is called with interrupts disabled. This patch is result of a discussion about using the API, see https://lkml.kernel.org/r/cfa886ad-e3b7-c0d2-3ff8-58d94170eab5@ti.com Reported-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Petr Mladek <pmladek@suse.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Tested-by: Grygorii Strashko <grygorii.strashko@ti.com> Acked-by: Tejun Heo <tj@kernel.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/20200217120709.1974-1-pmladek@suse.com Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
