I can't decipher them and would not want users see them in /proc.
Would nonvoluntary_ctxt_switch be that much worse?
I'm not too attached to a particular name. I just think that the
traditional counter names should pass readability/etc. criteria on
account of the very strong historical precedent. I'd consider more
verbose affairs for the sake of putative legibility as equivalent
in quality. Maybe that means others voting for the more verbose
names should result in an aggregate decision in favor of verbosity.

I can't say that "Nvcsw" and "Nivcsw" is something less verbose as
output above.
It is more usual so it is more clear for you. But if you need this counters
you should know what are they and how to use them.
As for me "nonvoluntary_ctxt_switch" and "voluntary_ctxt_switch" is more
verbose,
and it is not big deal to change names. But I think that information about
this counters and verbose name should be in user space tools, like ps.
