In this patch, we segregate flash only volume write streams from cached devices, so data from flash only volumes and cached devices can store in different buckets. Compare to v1 patch, this patch do not add a additionally open bucket list, and it is try best to segregate flash only volume write streams from cached devices, sectors of flash only volumes may still be mixed with dirty sectors of cached device, but the number is very small.

For example, after the following command: echo 1 >/sys/block/sdb/bcache/detach you can still see the writeback thread. Then you attach the device to the cache again, bcache will create another writeback thread, for example, after below command: echo ba0fb5cd-658a-4533-9806-6ce166d883b9 > /sys/block/sdb/bcache/attach then you will see 2 writeback threads. This patch stops writeback thread and cancels writeback_rate_update work when cached device detaching from cache. Compare with patch v1, this v2 patch moves code down into the register lock for safety in case of any future changes as Coly and Mike suggested.

The TD0245S specification requires that the chipselect is toggled between commands sent to the panel. This was also the purpose of the former patch of commit f64dcac0b124 ("backlight: tdo24m: ensure chip select changes between transfers"). Unfortunately, the "cs_change" field of a SPI transfer is misleading. Its true meaning is that for a SPI message holding multiple transfers, the chip select is toggled between each transfer, but for the last transfer it remains asserted. In this driver, all the SPI messages contain exactly one transfer, which means that each transfer is the last of its message, and as a consequence the chip select is never toggled. Actually, there was a second bug hidding the first one, hence the problem was not seen until v4.6. This problem was fixed by commit a52db659c79c ("spi: pxa2xx: Fix cs_change management") for PXA based boards. This fix makes the TD035S work again on a cm-x300 board. The same applies to other PXA boards, ie. corgi and tosa.

We have a situation where the userspace client is writing to the sysfs to update the power and since the callback function exists the client receives the return value as count and considers the operation to be successful. That is correct as the write to the sysfs was successful. But there is no way to know if the actual operation was done or not. backlight_update_status() returns the error code if it fails. Pass that to the userspace client who is trying to update the power so that the client knows that the operation failed.

Patch "arp: honour gratuitous ARP _replies_" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled arp: honour gratuitous ARP _replies_ to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arp-honour-gratuitous-arp-_replies_.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Mon Apr 9 17:09:24 CEST 2018 From: Ihar Hrachyshka <ihrachys(a)redhat.com> Date: Tue, 16 May 2017 07:53:43 -0700 Subject: arp: honour gratuitous ARP _replies_ From: Ihar Hrachyshka <ihrachys(a)redhat.com> [ Upstream commit 23d268eb240954e6e78f7cfab04f2b1e79f84489 ] When arp_accept is 1, gratuitous ARPs are supposed to override matching entries irrespective of whether they arrive during locktime. This was implemented in commit 56022a8fdd87 ("ipv4: arp: update neighbour address when a gratuitous arp is received and arp_accept is set") There is a glitch in the patch though. RFC 2002, section 4.6, "ARP, Proxy ARP, and Gratuitous ARP", defines gratuitous ARPs so that they can be either of Request or Reply type. Those Reply gratuitous ARPs can be triggered with standard tooling, for example, arping -A option does just that. This patch fixes the glitch, making both Request and Reply flavours of gratuitous ARPs to behave identically. As per RFC, if gratuitous ARPs are of Reply type, their Target Hardware Address field should also be set to the link-layer address to which this cache entry should be updated. The field is present in ARP over Ethernet but not in IEEE 1394. In this patch, I don't consider any broadcasted ARP replies as gratuitous if the field is not present, to conform the standard. It's not clear whether there is such a thing for IEEE 1394 as a gratuitous ARP reply; until it's cleared up, we will ignore such broadcasts. Note that they will still update existing ARP cache entries, assuming they arrive out of locktime time interval. Signed-off-by: Ihar Hrachyshka <ihrachys(a)redhat.com> Signed-off-by: David S.

Patch "ARM: imx: Add MXC_CPU_IMX6ULL and cpu_is_imx6ull" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: imx: Add MXC_CPU_IMX6ULL and cpu_is_imx6ull to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm-imx-add-mxc_cpu_imx6ull-and-cpu_is_imx6ull.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Mon Apr 9 17:09:24 CEST 2018 From: Leonard Crestez <leonard.crestez(a)nxp.com> Date: Tue, 6 Jun 2017 20:50:42 +0300 Subject: ARM: imx: Add MXC_CPU_IMX6ULL and cpu_is_imx6ull From: Leonard Crestez <leonard.crestez(a)nxp.com> [ Upstream commit b3ea575770c7eeb259c77b6861cd14d00eb309df ] Support for imx6ull is already present but it's based on of_machine_is_compatible("fsl,imx6ull") checks. Add it to the MXC_CPU_* enumeration as well. This also fixes /sys/devices/soc0/soc_id reading "Unknown".
