-Subject: [PATCH] RFC: media: Add media_request_{pin,unpin} API
-
-This is probably not the API we will want to add, but it
-should show what semantics are needed by drivers.
-
-The goal is to allow the OUTPUT (aka source) buffer and the
-controls associated to a request to be released from the request,
-and in particular return the OUTPUT buffer back to userspace,
-without signalling the media request fd.
-
-This is useful for devices that are able to pre-process
-the OUTPUT buffer, therefore able to release it before
-the decoding is finished. These drivers should signal
-the media request fd only after the CAPTURE buffer is done.
-
-Tested-by: John Cox <jc@kynesim.co.uk>
-Signed-off-by: Ezequiel Garcia <ezequiel@collabora.com>
