Merge tag 'ecryptfs-4.0-rc3-fixes' of git://git./linux/kernel/git/tyhicks/ecryptfs

Pull eCryptfs fixes from Tyler Hicks:
 "Fixes for proper ioctl handling and an untriggerable buffer overflow

   - The eCryptfs ioctl handling functions should only pass known-good
     ioctl commands to the lower filesystem

   - A static checker found a potential buffer overflow.  Upon
     inspection, it is not triggerable due to input validation performed
     on the mount parameters"

  eCryptfs: don't pass fs-specific ioctl commands through
  eCryptfs: ensure copy to crypt_stat->cipher does not overrun
