Its filename is zsmalloc-set-default-zspage-chain-size-to-8.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/zsmalloc-set-default-zspage-chain-size-to-8.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Sergey Senozhatsky 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.
