commit c59a5aca071806ce2ed7279bbaf78336da49ce85

    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 ]

commit 62c94547670f715923950a326daf8b129ca05ee5

    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.

commit b474c7ae4395ba684e85fde8f55c8cf44a39afaf

    xfs: Nuke XFS_ERROR macro
    
    XFS_ERROR was designed long ago to trap return values, but it's not
    runtime configurable, it's not consistently used, and we can do
    similar error trapping with ftrace scripts and triggers from
    userspace.
    
    Just nuke XFS_ERROR and associated bits.

    xfs: return is not a function
    
    return is not a function.  "return(EIO);" is silly;
    "return (EIO);" moreso.  return is not a function.
    Nuke the pointless parens.
    
    [dchinner: catch a couple of extra cases in xfs_attr_list.c,
    xfs_acl.c and xfs_linux.h.]
