From e84077437902ec99eba0a6b516df772653f142c7 Mon Sep 17 00:00:00 2001 From: Eliav Farber Date: Thu, 20 Oct 2022 12:44:58 +0000 Subject: EDAC/device: Fix period calculation in edac_device_reset_delay_period() Fix period calculation in case user sets a value of 1000. The input of round_jiffies_relative() should be in jiffies and not in milli-seconds. [ bp: Use the same code pattern as in edac_device_workq_setup() for clarity. ] Fixes: c4cf3b454eca ("EDAC: Rework workqueue handling") Signed-off-by: Eliav Farber Signed-off-by: Borislav Petkov (AMD) Cc: Link: https://lore.kernel.org/r/20221020124458.22153-1-farbere@amazon.com --- drivers/edac/edac_device.c | 17 ++++++++--------- drivers/edac/edac_module.h | 2 +- 2 files changed, 9 insertions(+), 10 deletions(-) (limited to 'drivers/edac') diff --git a/drivers/edac/edac_device.c b/drivers/edac/edac_device.c index 19522c568aa5..878deb4880cd 100644 --- a/drivers/edac/edac_device.c +++ b/drivers/edac/edac_device.c @@ -394,17 +394,16 @@ static void edac_device_workq_teardown(struct edac_device_ctl_info *edac_dev) * Then restart the workq on the new delay */ void edac_device_reset_delay_period(struct edac_device_ctl_info *edac_dev, - unsigned long value) + unsigned long msec) { - unsigned long jiffs = msecs_to_jiffies(value); - - if (value == 1000) - jiffs = round_jiffies_relative(value); - - edac_dev->poll_msec = value; - edac_dev->delay = jiffs; + edac_dev->poll_msec = msec; + edac_dev->delay = msecs_to_jiffies(msec); - edac_mod_work(&edac_dev->work, jiffs); + /* See comment in edac_device_workq_setup() above */ + if (edac_dev->poll_msec == 1000) + edac_mod_work(&edac_dev->work, round_jiffies_relative(edac_dev->delay)); + else + edac_mod_work(&edac_dev->work, edac_dev->delay); } int edac_device_alloc_index(void) diff --git a/drivers/edac/edac_module.h b/drivers/edac/edac_module.h index 763c076d96f2..47593afdc234 100644 --- a/drivers/edac/edac_module.h +++ b/drivers/edac/edac_module.h @@ -53,7 +53,7 @@ bool edac_stop_work(struct delayed_work *work); bool edac_mod_work(struct delayed_work *work, unsigned long delay); extern void edac_device_reset_delay_period(struct edac_device_ctl_info - *edac_dev, unsigned long value); + *edac_dev, unsigned long msec); extern void edac_mc_reset_delay_period(unsigned long value); /* -- cgit v1.2.3
