From 54e9e29132d7caefcad470281cae06ac34a982c8 Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Tue, 8 Sep 2015 15:00:39 -0700 Subject: mm, oom: pass an oom order of -1 when triggered by sysrq The force_kill member of struct oom_control isn't needed if an order of -1 is used instead. This is the same as order == -1 in struct compact_control which requires full memory compaction. This patch introduces no functional change.
