Merge tag 'configfs-for-linus' of git://git.infradead.org/users/hch/configfs

Pull configfs updates from Christoph Hellwig:

 - A large patch from me to simplify setting up the list of default
   groups by actually implementing it as a list instead of an array.

 - a small Y2083 prep patch from Deepa Dinamani.  Probably doesn't
   matter on it's own, but it seems like he is trying to get rid of all
   CURRENT_TIME uses in file systems, which is a worthwhile goal.

* tag 'configfs-for-linus' of git://git.infradead.org/users/hch/configfs:
  configfs: switch ->default groups to a linked list
  configfs: Replace CURRENT_TIME by current_fs_time()
