Here is another link that should give more insight on how most of the Linux I/O
stack has already been updated upstream and will be included in Fedora 13: http://lkml.org/lkml/2010/3/11/230
I think it is unfortunate that the time was taken to highlight Linux's preparedness
for 4K sector drives but failed to accurately convey the true state of the various
pieces involved. Even inaccurately concluding that there is much work ahead for
the various Linux tools.
The article focused on Tejun's misunderstanding and worked from there rather
than incorporating the more promising state of Linux's preparedness that was
revealed in reply to Tejun's post.
