+Subject: [PATCH 053/134] lowmemorykiller: Don't count free space unless it meets the specified limit by itself
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+This allows processes to be killed when the kernel evict cache pages in
+an attempt to get more contiguous free memory.
