    IMPORTANT:

    The definitions in this file were copied from <sys/vnode.h> in the Kernel framework in 

    the 10.4u SDK.  However, it is NOT important for these definitions to be kept in sync 

    with that header.  The goal of this file is to provide limited /source level/ compatibility 

    for code that is primarily designed for the kernel, but needs to be compiled for user 

    space for ancillary purposes.  It is /not/ meant to be binary compatible with the official 

    kernel definitions.

    A great example of this usage is the MFS core ("MFSCore.h" and "MFSCore.c").  This was meant 

    to be run in the kernel, and its interface and implementation are structured around that 

    goal.  However, on occasions were want to run the code in user space.  For example, the 

    MFSLives.util tool uses the code to probe a disk to see if it's MFS (and get the volume name).  

    Rather than cook up a different abstract interface to the MFS core, I decided to just 

    adapt the kernel interface for user space.
