From: Damien Le Moal <dlemoal@xxxxxxxxxx> For regular system shutdown, ata_dev_power_set_standby() will be executed twice: once the scsi device is removed and another when ata_pci_shutdown_one() executes and EH completes unloading the devices. Make the second call to ata_dev_power_set_standby() do nothing by using ata_dev_power_is_active() and return if the device is already in standby. Fixes: 2da4c5e24e86 ("ata: libata-core: Improve ata_dev_power_set_active()") Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Damien Le Moal <dlemoal@xxxxxxxxxx> Signed-off-by: Niklas Cassel <cassel@xxxxxxxxxx> --- This fix was originally part of patch that contained both a fix and a revert in a single patch: https://lore.kernel.org/linux-ide/20240111115123.1258422-3-dlemoal@xxxxxxxxxx/ This patch contains the only the fix (as it is valid even without the revert), without the revert. Updated the Fixes tag to point to a more appropriate commit, since we no longer revert any code. drivers/ata/libata-core.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index d9f80f4f70f5..af2334bc806d 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -85,6 +85,7 @@ static unsigned int ata_dev_init_params(struct ata_device *dev, static unsigned int ata_dev_set_xfermode(struct ata_device *dev); static void ata_dev_xfermask(struct ata_device *dev); static unsigned long ata_dev_blacklisted(const struct ata_device *dev); +static bool ata_dev_power_is_active(struct ata_device *dev); atomic_t ata_print_id = ATOMIC_INIT(0); @@ -2017,8 +2018,9 @@ void ata_dev_power_set_standby(struct ata_device *dev) struct ata_taskfile tf; unsigned int err_mask; - /* If the device is already sleeping, do nothing. */ - if (dev->flags & ATA_DFLAG_SLEEPING) + /* If the device is already sleeping or in standby, do nothing. */ + if ((dev->flags & ATA_DFLAG_SLEEPING) || + !ata_dev_power_is_active(dev)) return; /* -- 2.43.1
