The only real user of the T10 OSD protocol, the pNFS object layout
driver never went to the point of having shipping products, and we
removed it 1.5 years ago.  Exofs is just a simple example without
real life users.

The code has been mostly unmaintained for years and is getting in the
way of block / SCSI changes, so I think it's finally time to drop it.

Quote from Boaz:

"As I said then. It is used in Universities for studies and experiments.
Every once in a while. I get an email with questions and reports.

But yes feel free to remove the all thing!!

I think I'm changing my mind about this.

The osd driver was accepted in the upstream kernel in 2009. I have checked all
commits in Linus' tree for the osd driver that went in since 2009. All changes
made by other kernel developers than you are the result of tree-wide refactoring,
compiler warning fixes, fixes for issues detected by static source code
analyzers or spelling fixes. Hence my question: how big is the user base of the
exofs and osd kernel drivers? 

Not big at all. And none of them production setups. As I said mainly used
by academia.
