Subject: [GIT] Security changes for 2.6.29
Please pull the following security changes for 2.6.29.
The most significant changes here relate to the new credentials API from
David Howells. There will be conflicts with other trees, although these
should have been encountered in linux-next, and resolvable with patches
previously posted by sfr.
The following changes since commit 4a6908a3a050aacc9c3a2f36b276b46c0629ad91:
