Thanks for the explanation. I was pondering if the new size in power
of two could be a bit too excessive and the allocation step could be
linear, e.g. stick at 4096. target_id will increase linear,
therefore linear increase might also be enough, no?

Well, power-of-two resizing tends to behave relatively well under most
cases and slab allocations are binned by power-of-two sizes, so
linearly growing it doesn't really buy anything.

Convinced :)
