2020-09-21io_uring: don't use retry based buffered reads for non-async bdevJens Axboe
Some block devices, like dm, bubble back -EAGAIN through the completion handler. We check for this in io_read(), but don't honor it for when we have copied the iov. Return -EAGAIN for this case before retrying, to force punt to io-wq.

2020-09-21io_uring: don't re-setup vecs/iter in io_resumit_prep() is already thereJens Axboe
If we already have mapped the necessary data for retry, then don't set it up again. It's a pointless operation, and we leak the iovec if it's a large (non-stack) vec.

Since commits 653ee35ce6d5 ("can: hi311x: remove custom DMA mapped buffer") Fixes: df58525df395 ("can: mcp251x: remove custom DMA mapped buffer") both the hi3111x and the mcp251x driver don't make use of the DMA API any more. So we can safely remove the HAS_DMA dependency. While we're here, remove the unneeded CAN_DEV and SPI dependencies from the CAN_HI311X symbol, as the parent menus already have these dependencies.

This patch adds the support of the rx/tx errors CAN counters to the driver of the PCAN-USB PC-CAN interface from PEAK-System GmbH. The PCAN-USB is capable of giving back the values of the rx/tx errors counters, to provide more details and statistics to the linux-can layer.

2020-09-21can: pch_can: use generic power managementVaibhav Gupta
Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

2020-09-20bnxt_en: return proper error codes in bnxt_show_tempEdwin Peer
Returning "unknown" as a temperature value violates the hwmon interface rules. Appropriate error codes should be returned via device_attribute show instead. These will ultimately be propagated to the user via the file system interface. In addition to the corrected error handling, it is an even better idea to not present the sensor in sysfs at all if it is known that the read will definitely fail. Given that temp1_input is currently the only sensor reported, ensure no hwmon registration if TEMP_MONITOR_QUERY is not supported or if it will fail due to access permissions. Something smarter may be needed if and when other sensors are added.

Vladimir Oltean says: ==================== DSA with VLAN filtering and offloading masters This series attempts to make DSA VLANs work in the presence of a master interface that is: - filtering, so it drops VLANs that aren't explicitly added to its filter list - offloading, so the old assumptions in the tagging code about there being a VLAN tag in the skb are not necessarily true anymore. For more context: https://lore.kernel.org/netdev/20200910150738.mwhh2i6j2qgacqev@skbuf/ This probably marks the beginning of a series of patches in which DSA starts paying much more attention to its upper interfaces, not only for VLAN purposes but also for address filtering and for management of the CPU flooding domain.
