In the large picture, the problem is not so much about devices that restrict themselves to 8.3, such as DCIM-compatible cameras. They "only" accept 8.3, so there is no point in trying to use a long name because the software won't look for it in the first place. It is much more with devices that are commonly operated with long names - multimedia players come to mind - and these "always" want a valid 8.3. >> Perhaps camera vendors fear patents, too. > >quite likely they want to minimise their costs, and not paying for a >patent license they don't need is one way to do that. Well and there's always some vendors (the more so the one-product vendors) not paying the royalities they are supposed to. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
