20 | * This header is effectively a "namespace multiplexor" for the | |
21 | * user level XFS code. It provides all of the necessary stuff | |
22 | * such that we can build some parts of the XFS kernel code in | |
23 | * user space in a controlled fashion, and translates the names | |
24 | * used in the kernel into the names which libxfs is going to | |
25 | * make available to user tools. | |
26 | * | |
27 | * It should only ever be #include'd by XFS "kernel" code being | |
28 | * compiled in user space. | |
dfc130f3 | 29 | * |
2bd0ea18 NS |
30 | * Our goals here are to... |
31 | * o "share" large amounts of complex code between user and | |
32 | * kernel space; | |
33 | * o shield the user tools from changes in the bleeding | |
34 | * edge kernel code, merging source changes when | |
35 | * convenient and not immediately (no symlinks); | |
36 | * o i.e. be able to merge changes to the kernel source back | |
37 | * into the affected user tools in a controlled fashion; | |
38 | * o provide a _minimalist_ life-support system for kernel | |
39 | * code in user land, not the "everything + the kitchen | |
40 | * sink" model which libsim had mutated into; | |
41 | * o allow the kernel code to be completely free of code | |
42 | * specifically there to support the user level build. | |
