The series contains two patches:
 - add blocks_allocated to /proc/fs/ext4/<dev>/mb_stats
 - allow writing 0 to /proc/fs/ext4/<dev>/mb_stats to clear the current
   mballoc statistics

Changes since v2: 
 - Add mb_stats documentation to patch 2
 - Add Reviewed-by tags

Dear All,
    This commit adds the description of the ext4 proc parameter mb_stats 
to the corresponding documentation.
    I noticed that the documentation also lacks descriptions for the 
es_shrinker_info, fc_info, mb_structs_summary, and options parameters.
    However, these parameters are irrelevant to the work done in this 
series of patches.
    I will commit a separate patch later to explain the other parameters.
    This time, I only explain mb_stats.

    Thanks,
    Baolin
