#1387671 — Confusing olddefault prompt for Z3FOLD

[Multipart message — attachments visible in raw view] — view raw

Saw this duplicate prompt text in today's linux-next in a 'make oldconfig':

Low density storage for compressed pages (ZBUD) [Y/n/m/?] y
Low density storage for compressed pages (Z3FOLD) [N/m/y/?] (NEW) ?

I had to read the help texts for both before I clued in that one used
two compressed pages, and the other used 3.

And 'make oldconfig' doesn't have a "Wait, what?" option to go back
to a previous prompt....

(Change Z3FOLD prompt to "New low density" or something? )

Or even better can we only a single one rather than 2 algorithms doing
the similar thing? I wasn't following this closely but what is the
difference to have them both?
