[GIT PULL] eCryptfs fixes for 3.1-rc2

[Tyler Hicks]

Hi Linus,

John has added an eCryptfs mount option to do a mount time check
ensuring that the source mount point is owned by the real uid of the
process performing the mount. Roberto's Kconfig patch fixes a
dependency-based compile error when encrypted keys are built as a module
but eCryptfs is a built-in. My first patch removes a call to BUG() when
we should be returning an error and my second patch simply fixes a
compiler warning.

The following changes since commit 322a8b034003c0d46d39af85bf24fee27b902f48:
