Subject: zsmalloc: set default zspage chain size to 8
Date: Wed, 18 Jan 2023 09:52:10 +0900

This changes key characteristics (pages per-zspage and objects per-zspage)
of a number of size classes which in results in different pool
configuration.  With zspage chain size of 8 we have more size clases
clusters (123) and higher huge size class watermark (3632 bytes).

Please read zsmalloc documentation for more details.
