From 888022c0473d079bff9b47fb50434b1f20f8f37f Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Tue, 21 Feb 2017 14:21:01 +0100 Subject: dma-buf: add support for compat ioctl MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add compat ioctl support to dma-buf. This lets one to use DMA_BUF_IOCTL_SYNC ioctl from 32bit application on 64bit kernel. Data structures for both 32 and 64bit modes are same, so there is no need for additional translation layer.
