Hi,

>going to do it following your points.
After looking into existing code, I'm thinking Generation Memory Context
seems to have the similar purpose. So I'll implement ShmZoneContext
by reference it.
Generation context manages chunks having almost same life span.
ShmZoneContext would dsa_allocate() block and hand out chunks
and free chunks and its block all together.
Regards,
Takeshi Ideriha
