It's legal to have 'offset + len' equal to sizeof(struct virtio_net_config), since 'ndev->config' is a 'struct virtio_net_config', so we can safely copy its content under this condition.

In 'commit 29cc309d ("HID: hid-multitouch: forward MSC_TIMESTAMP")', EV_MSC/MSC_TIMESTAMP is added to each before EV_SYN event. EV_MSC is configured as INPUT_PASS_TO_ALL. In case of a touch device which report MSC_TIMESTAMP: BE pass EV_MSC/MSC_TIMESTAMP to FE on receiving event from evdev. FE pass EV_MSC/MSC_TIMESTAMP back to BE. BE writes EV_MSC/MSC_TIMESTAMP to evdev due to INPUT_PASS_TO_ALL. BE receives extra EV_MSC/MSC_TIMESTAMP and pass to FE. >>> Each new frame becomes larger and larger. Disable EV_MSC/MSC_TIMESTAMP forwarding for MT. V2: Rebase. Signed-off-by:

module parameter 'virtblk_queue_depth' was firstly introduced for testing/benchmarking purposes described in commit fc4324b4 ("virtio-blk: base queue-depth on virtqueue ringsize or module param"). And currently 'virtblk_queue_depth' is used as a saved value for the first probed device. Since we have different virtio-blk devices which have different capabilities, it requires that we support per-device queue depth instead of per-module. So defaultly use vq free elements if module parameter 'virtblk_queue_depth' is not set. Signed-off-by:

The size of 'struct vhost_scsi' is order-10 (~2.3MB). It may take long time delay by kzalloc() to compact memory pages by retrying multiple times when there is a lack of high-order pages. As a result, there is latency to create a VM (with vhost-scsi) or to hotadd vhost-scsi-based storage. The prior commit 595cb754 ("vhost/scsi: use vmalloc for order-10 allocation") prefers to fallback only when really needed, while this patch allocates with kvzalloc() with __GFP_NORETRY implicitly set to avoid retrying memory pages compact for multiple times. The __GFP_NORETRY is implicitly set if the size to allocate is more than PAGE_SZIE and when __GFP_RETRY_MAYFAIL is not explicitly set.

To add one or more VDPA devices, define a management device which allows adding or removing vdpa device. A management device defines set of callbacks to manage vdpa devices. To begin with, it defines add and remove callbacks through which a user defined vdpa device can be added or removed. A unique management device is identified by its unique handle identified by management device name and optionally the bus name. Hence, introduce routine through which driver can register a management device and its callback operations for adding and remove a vdpa device. Introduce vdpa netlink socket family so that user can query management device and its attributes. Example of show vdpa management device which allows creating vdpa device of networking class (device id = 0x1) of virtio specification 1.1 section 5.1.1. $ vdpa mgmtdev show vdpasim_net: supported_classes: net Example of showing vdpa management device in JSON format. $ vdpa mgmtdev show -jp { "show": { "vdpasim_net": { "supported_classes": [ "net" ] } } } Signed-off-by:Eric Dumazet <edumazet@google.com> Reported-by:

The leds-rt8515 driver can optionall use the v4l2 flash led class, but it causes a link error when that class is in a loadable module and the rt8515 driver itself is built-in: ld.lld: error: undefined symbol: v4l2_flash_init >>> referenced by leds-rt8515.c >>> leds/flash/leds-rt8515.o:(rt8515_probe) in archive drivers/built-in.a Adding 'depends on V4L2_FLASH_LED_CLASS' in Kconfig would avoid that, but it would make it impossible to use the driver without the v4l2 support. Add the same dependency that the other users of this class have instead, which just prevents the broken configuration. Fixes: e1c6edcb ("leds: rt8515: Add Richtek RT8515 LED driver") Signed-off-by:
