Merge tag 'ecryptfs-3.6-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs

Pull ecryptfs fixes from Tyler Hicks:
 - Fixes a bug when the lower filesystem mount options include 'acl',
   but the eCryptfs mount options do not
 - Cleanups in the messaging code
 - Better handling of empty files in the lower filesystem to improve
   usability.  Failed file creations are now cleaned up and empty lower
   files are converted into eCryptfs during open().
 - The write-through cache changes are being reverted due to bugs that
   are not easy to fix.  Stability outweighs the performance
   enhancements here.
 - Improvement to the mount code to catch unsupported ciphers specified
   in the mount options
