The Vma and ProcMemInfo objects do not need separate stats objects for storing working set. The Vma either has working set or memory usage information and never both. Bug: 111694435 Test: libmeminfo_test 1 Change-Id: I2df05f7e750bbba4325474633e705d6d68dd2ccb Merged-In: I2df05f7e750bbba4325474633e705d6d68dd2ccb Signed-off-by: Sandeep Patil <sspatil@google.com>
