From 9707aff701e325e7c4660409c43392ff2fb36fad Mon Sep 17 00:00:00 2001 From: Lu Jialin Date: Thu, 28 Apr 2022 23:16:00 -0700 Subject: mm/memcontrol.c: remove unused private flag of memory.oom_control There is no use for the private value, __OOM_TYPE and OOM notifier OOM_CONTROL. Therefore remove them to make the code clean.
