A bit of wikipedia reading turns up these indirect documentations of the solutions: http://arstechnica.com/information-technology/2009/07/vfat-linux-patch-could-circumvent-microsofts-patent-claims/ https://web.archive.org/web/20130131034455/http://www.desktoplinux.com/news/NS4980952387.html which in turn leads to this FAQ: https://web.archive.org/web/20121116185559/http://lkml.org/lkml/2009/6/26/314 So reading between the lines, IBM's opinion was that implementing a workaround that operates FAT in such a way that it never uses a common namespace was sufficient to avoid any legal questions about whether that code conflicts with a patent on a common namespace, sidestepping the longer question of any legal battle over the patent itself. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org Attachment:
