I pull the new V2 patchset, it works fine. I found another bug in libsas, will send out later. Jack [PATCH v2 28/28] libsas: don't recover 'gone' devices in > sas_ata_hard_reset() > > The commands that timeout when a disk is forcibly removed may trigger > libata to attempt recovery of the device. If libsas has decided to > remove the device don't permit ata to continue to issue resets to its > last known phy. > > The primary motivation for this patch is hotplug testing by writing 0 to > /sys/class/sas_phy/phyX/enable. Without this check this test leads to > libata issuing a reset and re-enabling the device that wants to be torn > down. > > Signed-off-by: Dan Williams <dan.j.williams@xxxxxxxxx> > --- > drivers/scsi/libsas/sas_ata.c | 3 +++ > 1 files changed, 3 insertions(+), 0 deletions(-) > > diff --git a/drivers/scsi/libsas/sas_ata.c b/drivers/scsi/libsas/sas_ata.c > index 96f316f..2814731 100644 > --- a/drivers/scsi/libsas/sas_ata.c > +++ b/drivers/scsi/libsas/sas_ata.c > @@ -321,6 +321,9 @@ static int sas_ata_hard_reset(struct ata_link *link, > unsigned int *class, > struct domain_device *dev = ap->private_data; > struct sas_internal *i = dev_to_sas_internal(dev); > > + if (dev->gone) > + return -ENODEV; > + > res = i->dft->lldd_I_T_nexus_reset(dev); > > if (res != TMF_RESP_FUNC_COMPLETE) > > -- > To unsubscribe from this list: send the line "unsubscribe linux-scsi" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
