hmm but we have FOLL_LONGTERM as an adjunct to FOLL_PIN (doesn't make senseI'm confused about the _READONLY, well. and the FOLL_PIN_NO_GUP_WRITE.
without - any checks that exist for that btw should be extended to this noew
flag).
Also don't we want to encode the legacy aspect here?
Maybe FOLL_LONGTERM_LEGACY_READONLY? Naming is hard :)
We want to longterm write-pin.
@Pankaj, how come you would call this "FOLL_PIN_NO_GUP_WRITE" -- why "no GUP
write" ?
Honestly, I did not finalize it then, just tossed the name for some suggestion :-)
I agree that someting like FOLL_LONGTERM_LEGACY_* is the right thing to do, but
I don't see where this is "no write" or "readonly" ?
Maybe FOLL_LONGTERM_LEGACY_, still pondering what that name could be ...
Thanks,
Pankaj
