-+ * Compatibility interface for userspace libc header coordination:
-+ *
-+ * Define compatibility macros that are used to control the inclusion or
-+ * exclusion of UAPI structures and definitions in coordination with another
-+ * userspace C library.
-+ *
-+ * This header is intended to solve the problem of UAPI definitions that
-+ * conflict with userspace definitions. If a UAPI header has such conflicting
-+ * definitions then the solution is as follows:
-+ *
-+ * * Synchronize the UAPI header and the libc headers so either one can be
-+ *   used and such that the ABI is preserved. If this is not possible then
-+ *   no simple compatibility interface exists (you need to write translating
-+ *   wrappers and rename things) and you can't use this interface.
-+ *
-+ * Then follow this process:
-+ *
-+ * (a) Include libc-compat.h in the UAPI header.
-+ *      e.g. #include <linux/libc-compat.h>
-+ *     This include must be as early as possible.
-+ *
-+ * (b) In libc-compat.h add enough code to detect that the comflicting
-+ *     userspace libc header has been included first.
-+ *
-+ * (c) If the userspace libc header has been included first define a set of
-+ *     guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
-+ *     set their values to 0.
-+ *
-+ * (d) Back in the UAPI header with the conflicting definitions, guard the
-+ *     definitions with:
-+ *     #if __UAPI_DEF_FOO
-+ *       ...
-+ *     #endif
-+ *
-+ * This fixes the situation where the linux headers are included *after* the
-+ * libc headers. To fix the problem with the inclusion in the other order the
-+ * userspace libc headers must be fixed like this:
-+ *
-+ * * For all definitions that conflict with kernel definitions wrap those
-+ *   defines in the following:
-+ *   #if !__UAPI_DEF_FOO
-+ *     ...
-+ *   #endif
-+ *
-+ * This prevents the redefinition of a construct already defined by the kernel.
