    kernel - change vfs.timestamp_precision default when hz < 100
    
    * Change the default for vfs.timestamp_precision to a more precise
      time calculation when hz is less than 100.  When hz is very low,
      the default tick-resolution filesystem timestamps become too
      granular and can often lead to make/Makefile issues.
    
      Thus, if hz is less than 100, we change the default from mode
      2 (uSec at ticks precision) to mode 4 (uSec at maximum precision).
