------------------------------------------------------
From: Joonsoo Kim <js1304@xxxxxxxxx>
Subject: mm/compaction.c: __compact_pgdat() code cleanuup
This patch uses is_via_compact_memory() to distinguish compaction from
sysfs or sysctl. And, this patch also reduces indentation on
compaction_defer_reset() by filtering these cases first before checking
watermark.
There is no functional change.
