Mel Gorman ed4a6d7f06 mm: compaction: add /sys trigger for per-node memory compaction
Add a per-node sysfs file called compact.  When the file is written to,
each zone in that node is compacted.  The intention that this would be
used by something like a job scheduler in a batch system before a job
starts so that the job can allocate the maximum number of hugepages
without significant start-up cost.
