From cd2e472e54a49c13b0a728cdda7c10c50421e23d Mon Sep 17 00:00:00 2001 From: Daniil Tatianin Date: Wed, 12 Feb 2025 17:39:19 +0300 Subject: system: introduce a new MlockState enum Replace the boolean value enable_mlock with an enum and add a helper to decide whether we should be calling os_mlock. This is a stepping stone towards introducing a new mlock mode, which will be the third possible state of this enum.
