I suggest you work with whatever group is forcing you to use this old kernel version as they are the ones that you are paying to support this kernel for you. If you wish to discuss the 4.7 or newer kernel versions, and how ion works there (look in linux-next for the most recent changes in that area), we would be glad to help you out. Best of luck! greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
