From: Jes Sorensen <jsoren...@fb.com> smi_mod_timer() enables the timer before setting timer_running. This means the timer can be running when we get to stop_timer_and_thread() without timer_running having been set, resulting in del_timer_sync() not being called and the timer being left to cause havoc during shutdown.
Instead just call del_timer_sync() unconditionally Signed-off-by: Jes Sorensen <jsoren...@fb.com> --- drivers/char/ipmi/ipmi_si_intf.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/char/ipmi/ipmi_si_intf.c b/drivers/char/ipmi/ipmi_si_intf.c index da5b6723329a..53425e25ecf4 100644 --- a/drivers/char/ipmi/ipmi_si_intf.c +++ b/drivers/char/ipmi/ipmi_si_intf.c @@ -1828,8 +1828,7 @@ static inline void stop_timer_and_thread(struct smi_info *smi_info) } smi_info->timer_can_start = false; - if (smi_info->timer_running) - del_timer_sync(&smi_info->si_timer); + del_timer_sync(&smi_info->si_timer); } static struct smi_info *find_dup_si(struct smi_info *info) -- 2.21.0
