| * block/sd: Return -EREMOTEIO when WRITE SAME and DISCARD are disabledMartin K. Petersen2016-02-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a storage device rejects a WRITE SAME command we will disable write same functionality for the device and return -EREMOTEIO to the block layer. -EREMOTEIO will in turn prevent DM from retrying the I/O and/or failing the path. Yiwen Jiang discovered a small race where WRITE SAME requests issued simultaneously would cause -EIO to be returned. This happened because any requests being prepared after WRITE SAME had been disabled for the device caused us to return BLKPREP_KILL. The latter caused the block layer to return -EIO upon completion. To overcome this we introduce BLKPREP_INVALID which indicates that this is an invalid request for the device. blk_peek_request() is modified to return -EREMOTEIO in that case.

The commit causes the system to splat out following errors continuously without ever reaching the UI: ata14.00: configured for UDMA/66 ata14: EH complete ata14.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 ata14.00: irq_stat 0x40000001 ata14.00: cmd a0/01:00:00:00:01/00:00:00:00:00/a0 tag 6 dma 16640 in Inquiry 12 01 00 00 ff 00res 00/00:00:00:00:00/00:00:00:00:00/00 Emask 0x3 (HSM violation) ata14: hard resetting link ata14: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata14.00: configured for UDMA/66 ata14: EH complete ata14.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 ata14.00: irq_stat 0x40000001 ata14.00: cmd a0/01:00:00:00:01/00:00:00:00:00/a0 tag 7 dma 16640 in Inquiry 12 01 00 00 ff 00res 00/00:00:00:00:00/00:00:00:00:00/00 Emask 0x3 (HSM violation) Without in-depth understanding of SCSI layer and the Marvell controller, I suspect this happens because when the link goes down (because of an error) we schedule scsi_rescan_device() which again fails to read VPD data... ad infinitum. Since VPD data cannot be read from the device anyway we prevent the SCSI layer from even trying by blacklisting the device. This gets away the error and the system starts up normally.

| | | | | | | | | | | | | | | | | | | | | | | | | | If MODE SELECT returns with sense '05/91/36' (command lock violation) it should always be retried without counting the number of retries. During an HBA upgrade or similar circumstances one might see a flood of MODE SELECT command from various HBAs, which will easily trigger the sense code and exceed the retry count.

* | SCSI: fix crashes in sd and sr runtime PMAlan Stern2016-01-272-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Runtime suspend during driver probe and removal can cause problems. The driver's runtime_suspend or runtime_resume callbacks may invoked before the driver has finished binding to the device or after the driver has unbound from the device. This problem shows up with the sd and sr drivers, and can cause disk or CD/DVD drives to become unusable as a result. The fix is simple. The drivers store a pointer to the scsi_disk or scsi_cd structure as their private device data when probing is finished, so we simply have to be sure to clear the private data during removal and test it during runtime suspend/resume.

This fixes a problem that the system is cool, while the fan devices are left running on full speed after boot, if fan device is registered after thermal zone device. Here is the history of why current patch looks like this: https://patchwork.kernel.org/patch/7273041/ CC: <stable@vger.kernel.org> #3.18+ Reference:https://bugzilla.kernel.org/show_bug.cgi?id=92431 Tested-by: Manuel Krause <manuelkrause@netscape.net> Tested-by: szegad <szegadlo@poczta.onet.pl> Tested-by: prash <prash.n.rao@gmail.com> Tested-by: amish <ammdispose-arch@yahoo.com> Reviewed-by: Javi Merino <javi.merino@arm.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Chen Yu <yu.c.chen@intel.com>

Thus, the proper way to do this is to cancel all thermal zone device update requirements during suspend/resume, and after all the devices have been resumed, reset and update every registered thermal zone devices. This also fixes a regression introduced by: Commit 19593a1fb1f6 ("ACPI / fan: convert to platform driver") Because, with above commit applied, all the fan devices are attached to the acpi_general_pm_domain, and they are turned on by the pm_domain automatically after resume, without the awareness of thermal core.

In this case, we need specially handling for the first thermal_zone_device_update(). Both thermal core framework and step_wise governor is enhanced to handle this. And since the step_wise governor is the only one that uses trends, so it's the only thermal governor that needs to be updated.
