Date: Tue, 31 May 2022 10:41:05 +0200 Message-ID: <10087857.nUPlyArG6x@bagend> Organization: Connecting Knowledge In https://bugs.debian.org/970639 the request was made to enable ZSWAP. Upon it was (rightly) noted that zswap.rst contained this: > Zswap is a new feature as of v3.11 and interacts heavily with memory > reclaim. This interaction has not been fully explored on the large set > of potential configurations and workloads that exist. For this reason, > zswap is a work in progress and should be considered experimental. Furthermore the mm/Kconfig contains this on the ZSWAP option: > Compressed cache for swap pages (EXPERIMENTAL) But the contents of that zswap.rst hasn't changed since the initial commit 61b0d76017a50c263c303fa263b295b04e0c68f6 from 2013-07-11. Similarly, that line in Kconfig hasn't changed either since the initial commit 2b2811178e85553405b86e3fe78357b9b95889ce from 2013-07-11. Should ZSWAP should still be considered experimental or not?
