From 62fed26ff4338eeccc702799be358bbb1471b76c Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 21 May 2018 04:54:44 -0400 Subject: media: videodev2.h: Add request_fd field to v4l2_buffer When queuing buffers allow for passing the request that should be associated with this buffer. If V4L2_BUF_FLAG_REQUEST_FD is set, then request_fd is used as the file descriptor. If a buffer is stored in a request, but not yet queued to the driver, then V4L2_BUF_FLAG_IN_REQUEST is set.
