34 * This header is effectively a "namespace multiplexor" for the
35 * user level XFS code. It provides all of the necessary stuff
36 * such that we can build some parts of the XFS kernel code in
37 * user space in a controlled fashion, and translates the names
38 * used in the kernel into the names which libxfs is going to
39 * make available to user tools.
40 *
41 * It should only ever be #include'd by XFS "kernel" code being
42 * compiled in user space.
43 *
44 * Our goals here are to...
45 * o "share" large amounts of complex code between user and
46 * kernel space;
47 * o shield the user tools from changes in the bleeding
48 * edge kernel code, merging source changes when
49 * convenient and not immediately (no symlinks);
50 * o i.e. be able to merge changes to the kernel source back
51 * into the affected user tools in a controlled fashion;
52 * o provide a _minimalist_ life-support system for kernel
53 * code in user land, not the "everything + the kitchen
54 * sink" model which libsim had mutated into;
55 * o allow the kernel code to be completely free of code
56 * specifically there to support the user level build.
