Add a write-only mb_stats_clear sysfs knob to reset ext4 mballoc
runtime statistics.This makes it easier to inspect allocator
activity for a specific workload instead of using counters
accumulated since mount.

Make sense to me. The changes looks good and works fine at my end.
So please feel free to add:
