A bit of wikipedia reading turns up these indirect documentations of the solutions: http://arstechnica.com/information-technology/2009/07/vfat-linux-patch-co= uld-circumvent-microsofts-patent-claims/ https://web.archive.org/web/20130131034455/http://www.desktoplinux.com/ne= ws/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. --=20 Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --pCgrkhGE72QdaH3b8mtqortqTQdEe5Hp8 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJV8j8EAAoJEKeha0olJ0Nq5N4H/itB53viSvqV0EuUertzcX0Y MxBq1zBsmtkccb1205f78+N4BJw2ou1A1+0O6pEHc5W0nSICekAGIleNvOEvKc33 tROFOZyQBMNdsEpU2Ay1MTinotDNN1xCxdrgZwk3rYXHE2tEGI639f/RnQJ/HztT BgU3qKI1izXzT+jbPc+0//X6olhgyt3Qw6LTnsEWN+YzJhxeWkxn61BqdoliZE7y v9P+fXNe5GCcdESR4QdW2DLUYT48xlKrbL5Whjuo6MGZQtik3Iq3Lhdwynd1AeQP V3h+8QAEHEtgHxsq9zHQMcSqWPwRnRhBaNQhi/tz5O9l4icWGNiGESaFdFQba3M= =wtfD -----END PGP SIGNATURE----- --pCgrkhGE72QdaH3b8mtqortqTQdEe5Hp8--
