- Request api allows to synchronize controls along with buffers. - Client allocates a request fd. This request fd is associated with control and set using s_ext_ctrls. Such controls are stored by the framework and not applied immediately. - Request fd is also associated with input qbuf and queued to driver. Following this actual request is queued. Buffers do not enter the queue untill the request is queued. - As part of qbuf, driver call request_setup() which inturn sets the control to driver.
