[PATCH] staging: android: ion: add buffer flag update ioctl

In some usecases, the buffer cached attribute is not determined at allocation time, it's determined just before the real cpu mapping. And from the memory view of point, a buffer should not have the cached attribute util is really mapped by the cpu. So in this patch, we introduced the new ioctl

[PATCH v3 0/6] usb: gadget: add mechanism to asynchronously validate data stage of ctrl out request

This patch series adds a mechanism to allow asynchronously validating the data stage of a control OUT request, and for stalling or suceeding the request accordingly. This mechanism is implemented for MUSB, and is used by UVC. At the same time, UVC packages the setup stage and data stage data

[PATCH v3 2/6] usb: gadget: uvc: enqueue usb request in setup handler for control OUT

Currently, for uvc class-specific control IN and OUT requests, in the setup handler a UVC_EVENT_SETUP with the setup control is enqueued to userspace. In response to this, the uvc function driver expects userspace to call ioctl UVCIOC_SEND_RESPONSE containing uvc request data. In the case of

[PATCH v3 6/6] usb: gadget: uvc: allow ioctl to send response in status stage

We now have a mechanism to signal the UDC driver to reply to a control OUT request with STALL or ACK, and we have packaged the setup stage data and the data stage data of a control OUT request into a single UVC_EVENT_DATA for userspace to consume. The ioctl UVCIOC_SEND_RESPONSE in the case of a

[PATCH v3 4/6] usb: gadget: add mechanism to specify an explicit status stage

A usb gadget function driver may or may not want to delay the status stage of a control OUT request. An instance it might want to is to asynchronously validate the data of a class-specific request. A function driver that wants an explicit status stage should set the newly added explicit_status

[PATCH v3 3/6] usb: gadget: uvc: package setup and data for control OUT requests

Since "usb: gadget: uvc: enqueue uvc_request_data in setup handler for control OUT requests" it is no longer necessary for userspace to call ioctl UVCIOC_SEND_RESPONSE in response to receiving a UVC_EVENT_SETUP from the uvc function driver for a control OUT request. This change means that for
