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.
