Hi, All
Do we have special reason to keep this patch (316ba5736c9:brd: Mark as
non-rotational).
which leads to a performance regression when BRD is used as a disk on btrfs.

Since the functionality of zone_statistics() updates numa counters, but
numa statistics has been separated from zone statistics framework. Thus,
the function name makes people confused. So, change the name to
numa_statistics() as well as its call sites accordingly.
