As I mentioned in IRC, I came up with the same patch last night and
successfully ran tests against it overnight. We'll go with your patch
since it already has a commit message. I targeted it for 3.11+ stable
and will push it to Linus today. I'll also get the Ubuntu SRU prepared.

Tyler, reduced it down to a one line fix. Tested with a 0.5GB, 2GB, 4GB,
8GB, 32GB test file with a sanity check on each byte. Patch attached
below. Not yet tested with ecryptfs tests, but it looks like the root
issue.

Tyler, the attached diff helps me read/write files over 4GB. I think
some of the changes may be redundant, so I'm checking to see what is the
minimal set of changes required.
