From 98d3b6d98f8013d4e96f40d8d4b22d4da0d3f699 Mon Sep 17 00:00:00 2001 From: Xiongwei Song Date: Fri, 15 Dec 2023 11:41:50 +0800 Subject: mm/slub: make the description of slab_min_objects helpful in doc There is no a value assigned to slab_min_objects by default, it always is 0 that is initialized by compiler if no assigned value by command line. min_objects is calculated based on processor numbers in calculate_order(). For more details, see commit 9b2cd506e5f2 ("slub: Calculate min_objects based on number of processors.")
