From c7355d755698a01ff4187a0d2f6ad21ba233dc21 Mon Sep 17 00:00:00 2001 From: Vlastimil Babka Date: Fri, 8 Sep 2023 09:57:13 +0200 Subject: [PATCH] mm/slub: simplify the last resort slab order calculation If calculate_order() can't fit even a single large object within slub_max_order, it will try using the smallest necessary order that may exceed slub_max_order but not MAX_ORDER. Currently this is done with a call to calc_slab_order() which is unnecessary. We can simply use get_order(size). No functional change.
