Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs

Says Tyler:
 "Tim's logging message update will be really helpful to users when
  they're trying to locate a problematic file in the lower filesystem
  with filename encryption enabled.

  You'll recognize the fix from Li, as you commented on that.

  You should also be familiar with my setattr/truncate improvements,
  since you were the one that pointed them out to us (thanks again!).
  Andrew noted the /dev/ecryptfs write count sanitization needed to be
  improved, so I've got a fix in there for that along with some other
  less important cleanups of the /dev/ecryptfs read/write code."
