Re: [PATCH v3 00/26] Introduce common headers for vDSO

Hi Vincenzo, all

I like the idea, but I'm wondering if we could have less-grained
headers? Like, AFAICS the patches create headers < 10 lines and even
mostly < 5 lines.. I like that header's names perfectly describe what's
inside, but I'm not sure how effective to have a lot of extra-small
includes.

Or maybe there's a plan to grow the code in them?

Maybe we could made them less-grained?

I.e, time32 + time64 + time.h => time.h?
