From 5b36577109be007a6ecf4b65b54cbc9118463c2b Mon Sep 17 00:00:00 2001 From: Yang Shi Date: Wed, 15 Nov 2017 17:32:03 -0800 Subject: mm: slabinfo: remove CONFIG_SLABINFO According to discussion with Christoph (https://marc.info/?l=linux-kernel&m=150695909709711&w=2), it sounds like it is pointless to keep CONFIG_SLABINFO around. This patch removes the CONFIG_SLABINFO config option, but /proc/slabinfo is still available.
