If I were to guess the 3 primary reasons for that:
  1) the series is too large for anyone to actually read it all without
     being paid to do so
  2) the sysfs code is at the end of a huge debugfs patch, which
     probably noone cares about whether they are paid or not
  3) the small sysfs patch is so full of minor issues to nit about that
     it seems pointless to even start

But since I looked at it, I can name a few other obvious issues with the
sysfs patch:
 - mix of macro and octal mode values
 - no documentation (required for all new sysfs attributes according to
    Documentation/filesystems/sysfs.txt)
 - extremely dubious kboject usage and attribute creation/deletion (How
    does this fit into the driver model?  How will userspace race with
    these attributes being added and removed?)

I am sure there are plenty more.
