Since this is uAPI I think we need a better name?
TERSE_DUMP doesn't explain much, my first thought was that you'll just
trim some ancient attributes to make things smaller. Sounds like you
want it to be lockless. Also GET will effectively support this bit
too so _DUMP is a lie.

Maybe RTEXT_FILTER_LOCKLESS or RTEXT_FILTER_NAME_ONLY ?
