[GIT] New Credentials API (preliminary patches for 2.6.27)

From: James Morris
Date: Fri Jul 25 2008 - 16:08:12 EST

A new credentials framework has been developed by David Howells. The code
has been through several iterations of posting and review, and is
considered by various folk to be ready to merge into linux-next.

The problem is that these changes touch a lot of code and it will be
difficult to manage the volume of merge conflicts. I tried doing so
myself for a couple of weeks and there was non-trivial churn virtually
each day.

It seems that this can be managed more readily if the API changes are
merged upstream first as no-ops, as this is where most of the conflicts
were happening. The following patchset implements the no-op API changes,
as well as a fix to the use of PF_SUPERPRIV which was part of the larger
patchset but should also go in sooner rather than later.

Please pull.

The following changes since commit fb2e405fc1fc8b20d9c78eaa1c7fd5a297efde43:
Adrian Bunk (1):
fix fs/nfs/nfsroot.c compilation
