2020-09-21dax: Fix compilation for CONFIG_DAX && !CONFIG_FS_DAXJan Kara
dax_supported() is defined whenever CONFIG_DAX is enabled. So dummy implementation should be defined only in !CONFIG_DAX case, not in !CONFIG_FS_DAX case. Fixes: e2ec51282545 ("dm: Call proper helper to determine dax support") Cc: <stable@vger.kernel.org> Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Reported-by: Naresh Kamboju <naresh.kamboju@linaro.org> Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2020-09-21io_uring: fix openat/openat2 unified prep handlingJens Axboe
A previous commit unified how we handle prep for these two functions, but this means that we check the allowed context (SQPOLL, specifically) later than we should. Move the ring type checking into the two parent functions, instead of doing it after we've done some setup work. Fixes: ec65fea5a8d7 ("io_uring: deduplicate io_openat{,2}_prep()") Reported-by: Andy Lutomirski <luto@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-09-21io_uring: mark statx/files_update/epoll_ctl as non-SQPOLLJens Axboe
These will naturally fail when attempted through SQPOLL, but either with -EFAULT or -EBADF. Make it explicit that these are not workable through SQPOLL and return -EINVAL, just like other ops that need to use ->files. Signed-off-by: Jens Axboe <axboe@kernel.dk>

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.

2020-09-21wcn36xx: Remove dead code in wcn36xx_smd_config_bss()Bryan O'Donoghue
wcn36xx_smd_config_bss_v0() and wcn36xx_smd_config_bss_v1() have been designed to operate in standalone fashion. As a result we can drop the dead code now present in wcn36xx_smd_config_bss() and happily remove one kzalloc from the BSS config path as we do so.

2020-09-21wcn36xx: Update wcn36xx_smd_config_bss_v1() to operate internallyBryan O'Donoghue
This patch updates wcn36xx_smd_config_bss_v1() to update on internally derived parameters only, specifically making use of STA v1 wrapper routines previously added. Once done we no longer need to pass a struct wcn36xx_hal_config_bss_req_msg which gives us options in later patches to eliminate the kzalloc() in wcn36xx_smd_config_bss entirely.

In order to pass VHT parameters to wcn3680 we need to use a super-set of the V1 data-structures with additional VHT parameters tacked on. This patch adds the additional fields to the STA and BSS parameter structures. Since neither wcn3620 nor wcn3660 support VHT the size of the passed message is fixed to the previous message length. Subsequent changes will differentiate between wcn3620/wcn3660 and wcn3680 which does use the larger message size.

usb_kill_anchored_urbs() Calls to usb_kill_anchored_urbs() after usb_kill_urb() on multiprocessor systems create a race condition in which usb_kill_anchored_urbs() deallocates the URB before the completer callback is called in usb_kill_urb(), resulting in a use-after-free.

2020-09-21can: rx-offload: can_rx_offload_add_manual(): add new initialization functionMarc Kleine-Budde
This patch adds a new initialization function: can_rx_offload_add_manual() It should be used to add support rx-offload to a driver, if the callback mechanism should not be used. Use e.g. can_rx_offload_queue_sorted() to queue skbs into rx-offload.

2020-09-21can: mcp251x: add support for half duplex controllersTim Harvey
Some SPI host controllers do not support full-duplex SPI and are marked as such via the SPI_CONTROLLER_HALF_DUPLEX controller flag. For such controllers use half duplex transactions but retain full duplex transactions for the controllers that can handle those.
