I dont think SNIA defines RAID 10, which is a specific Linux MD thing.

Either you're very young, or don't read what I type, maybe both. ;)  RAID 10 has
been around for 15+ years.  It is not unique to Linux mdraid.  The "alternate
layouts" of mdraid are unique to Linux/mdraid, but RAID 10 is not unique to mdraid.

For RAID1+0, I think it is covered by the DDF standard

RAID 10 and RAID 1+0 are the same thing by two different names.  It's not

I'm getting dizzy from the running in circles...

Dope-slaps all 'round!

Again, this problem would just go away if everyone would just refrain
from using "RAID 10" or "RAID10" as if they were meaningful - within
the context of this list, they just cause confusion.

It seems the mdadm people are willing to use RAID 1+0 for "the other
kind", and the "outsiders" are willing to use "md RAID10", but both
sides would like to claim just plain "RAID10" for themselves, and it's
causing endless loops of non-communication!

Please reply with better alternatives, but IMO "md raid10" and
"raid1+0" are clear enough to be understood by one and all.

For those of you sick of my ranting on beating a dead horse, I'm sorry
but I just can't help keeping on trying to put this behind us - we're
all here for a common cause aren't we?

I'm not asking you to change any religious beliefs outside the list,
just adopt an enabling convention for discussions here.

I can agree with what is said here, at least when we are discussing with
somebody like Stan who insists on using terminology, that is easily
misunderstood. I do think precise terminology is important.
Also I have tried to clean up terminology other places, such as 
our wiki and in articles elsewhere. I tend to write "Linux MD raid10"
in those instances.
