Sorry Andrew, would you mind doing one more quick spin? :(  

No problem.

Thanks!

More importantly we should not use the ENOTSUPP error code, AFAIU it's
for NFS, it's not a standard error code and user space struggles to
translate it with strerror(). Would you mind replacing all ENOTSUPPs
with EOPNOTSUPPs?  

O.K.

Would it be worth getting checkpatch warning about this?

Good point. I feel like I already had a patch for it once, it must have
gotten lost when I was changing jobs. I'll take care of it.
