From 422ff4d70c1b3b2deed431dc095432dc691f4269 Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Thu, 5 Nov 2015 18:45:46 -0800 Subject: mm/slub: correct the comment in calculate_order() In calculate_order(), it tries to calculate the best order by adjusting the fraction and min_objects. On each iteration on min_objects, fraction iterates on 16, 8, 4. Which means the acceptable waste increases with 1/16, 1/8, 1/4. This patch corrects the comment according to the code.
