-Why:   V4L1 AP1 was replaced by V4L2 API during migration from 2.4 to 2.6
-       series. The old API have lots of drawbacks and don't provide enough
-       means to work with all video and audio standards. The newer API is
-       already available on the main drivers and should be used instead.
-
-       The userspace libv4l1 library can convert V4L1 calls to V4L2. This
-       replaces the kernel V4L1 compatibility module which was removed in
-       2.6.38. The last V4L1 drivers will either be converted to V4L2 or
-       removed for 2.6.39 at which point the V4L1 API will cease to exist.

+What:  Video4Linux: Remove obsolete ioctl's
+When:  kernel 2.6.39
+Files: include/media/videodev2.h
+Why:   Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
+       type of R/W arguments. They were fixed, but the old ioctl names are
+       still there, maintained to avoid breaking binary compatibility:
+         #define VIDIOC_OVERLAY_OLD    _IOWR('V', 14, int)
+         #define VIDIOC_S_PARM_OLD     _IOW('V', 22, struct v4l2_streamparm)
+         #define VIDIOC_S_CTRL_OLD     _IOW('V', 28, struct v4l2_control)
+         #define VIDIOC_G_AUDIO_OLD    _IOWR('V', 33, struct v4l2_audio)
+         #define VIDIOC_G_AUDOUT_OLD   _IOWR('V', 49, struct v4l2_audioout)
+         #define VIDIOC_CROPCAP_OLD    _IOR('V', 58, struct v4l2_cropcap)
+       There's no sense on preserving those forever, as it is very doubtful
+       that someone would try to use a such old binary with a modern kernel.
+       Removing them will allow us to remove some magic done at the V4L ioctl
+       handler.
