Which no one single piece of common code is using yet in 2.4.5pre1 so right now (2.4.5pre1) you must be doing the mainteinance yourself the old way. But I certainly agree that it is promising and that in the future de-localizing the 32bit wrappers is a good thing so at least people will see this code when they break it while changing the common code ;). > I'm already planning on doing this, but it is a 2.5.x project. > Dave Mosberger agrees with this as has anyone else I've mentioned > the idea to, so consider it basically done in 2.5.x sometime. Nice to hear that, when you do that please keep patches@x86-64.org in CC so we follow it. After we change the wrapper mechanism by avoiding the mainteinance work by de-localizing the wrappers and after we share the wrapper logic as well, it will be a _real_ pleasure to support the lvm ioctl from 32bit userland on x86-64 too indeed and then it will be a worthwhile effort to support those ioctl.
