commit 2451337dd043901b5270b7586942abe564443e3d
Author: Dave Chinner <dchinner@redhat.com>

    xfs: global error sign conversion
    
    Convert all the errors the core XFs code to negative error signs
    like the rest of the kernel and remove all the sign conversion we
    do in the interface layers.
    
    Errors for conversion (and comparison) found via searches like:
    
    $ git grep " E" fs/xfs
    $ git grep "return E" fs/xfs
    $ git grep " E[A-Z].*;$" fs/xfs
    
    Negation points found via searches like:
    
    $ git grep "= -[a-z,A-Z]" fs/xfs
    $ git grep "return -[a-z,A-D,F-Z]" fs/xfs
    $ git grep " -[a-z].*;" fs/xfs
    
    [ with some bits I missed from Brian Foster ]

    libxfs: move source files
    
    Move all the source files that are shared with userspace into
    libxfs/. This is done as one big chunk simpy to get it done
    quickly

commit 69116a1317ce3d2292e062bfb1a22757b95dcd06

    xfs: create libxfs infrastructure
    
    To minimise the differences between kernel and userspace code,
    split the kernel code into the same structure as the userspace code.
    That is, the gneric core functionality of XFS is moved to a libxfs/
    directory and treat it as a layering barrier in the XFS code.
    
    This patch introduces the libxfs directory, the build infrastructure
    and an initial source and header file to build. The libxfs directory
    will contain the header files that are needed to build libxfs - most
    of userspace does not care about the location of these header files
    as they are accessed indirectly. Hence keeping them inside libxfs
    makes it easy to track the changes and script the sync process as
    the directory structure will be identical.
    
    To allow this changeover to occur in the kernel code, there are some
    temporary infrastructure in the makefiles to grab the header
    filesystem from both locations. Once all the files are moved,
    modifications will be made in the source code that will make the
    need for these include directives go away.
