Bug 1011350 - Add mfbt support for PR_SET_VMA_ANON_NAME. r=njn r=froydnj This is a Linux kernel feature present in newer Android and B2G devices which allows attaching an arbitrary name to an anonymous memory regions, thus tagging it for the purposes of procfs mapping lists and causing it to be reported separately from adjacent regions with different names.
