From: Arnd Bergmann Date: Mon, 9 Jan 2006 17:24:57 +0000 (-0200) Subject: V4L (926_2): Moves compat32 functions from fs to v4l subsystem X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0d0fbf8152fb3bb4393be11e8df7f70e1fbbd738;p=linux.git V4L (926_2): Moves compat32 functions from fs to v4l subsystem This moves the 32 bit ioctl compatibility handlers for Video4Linux into a new file and adds explicit calls to them to each v4l device driver. Unfortunately, there does not seem to be any code handling the v4l2 ioctls, so quite often the code goes through two separate conversions, first from 32 bit v4l to 64 bit v4l, and from there to 64 bit v4l2. My patch does not change that, so there is still much room for improvement. Also, some drivers have additional ioctl numbers, for which the conversion should be handled internally to that driver.
