I'd keep "_partition" for clarity.

[Primiano Tucci (use gerrit), 2015/09/08 07:56:56]

I did remove it because the dump path is now:

partition_alloc/partitions/fast_malloc_partition etc I felt it was a bit
redundant having "partition" twice in the name.
WDYT? Restored in the meanwhile

[haraken, 2015/09/08 08:07:33]

ah, makes sense. Let's drop "_partition".

+    partitionDumpStatsGeneric(bufferPartition(), "buffer", isLightDump, partitionStatsDumper);
+    partitionDumpStats(nodePartition(), "node", isLightDump, partitionStatsDumper);
+    partitionDumpStats(layoutPartition(), "layout", isLightDump, partitionStatsDumper);
 }
