Urk, no. This will result in older applications picking up the new ioctl when they are rebuilt without having explicit support for the new ioctl. Just create a new ioctl with a new name and modify applications to use it. If the kernel does not support the new ioctl, then fall back to the old one in userspace. -Dave. -- Dave Chinner david@xxxxxxxxxxxxx _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
