[PATCHv2 4/4] zsmalloc: set default zspage chain size to 8
From: Sergey Senozhatsky
Date: Sun Jan 08 2023 - 22:40:06 EST
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.
