But since it's a device file and if you don't have a fixed major number that could be a problem since you wouldn't want to change any other device files behavior with your installation of file ops. Have you thought of doing a server/client instead of doing it via NFS. If it's just GPU you care about maybe you can have a client/server of your own that can communicate for the GPU exclusively. Perhaps you can give it a try and then see if NFS is better option. > -Riya > > On Sat, May 31, 2014 at 11:35 PM, Pranay Srivastava <pranjas@xxxxxxxxx> wrote: >> Hi Riya, >> >> It's actually not the major and minor numbers, sure they decide the >> driver and the device but when it comes to read/write you actually >> have file_operations.
