Subject: zsmalloc: set default zspage chain size to 8
Date: Mon, 9 Jan 2023 12:38:38 +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.
