+ * The following macros allow you to export symbols from vmkernel,

+ *
+ * The versions with no explicit name-space and version imply the
+ * default vmkernel name-space/version. They should be considered
+ * deprecated as they impede your ability to create very stable APIs.
+ *
+ * Sample usage:
+ *
+ * VMK_KERNEL_EXPORT(foo) : export foo
+ *
+ * VMK_KERNEL_ALIAS(foo, fooAlias) : export foo as fooAlias
+ *
+ * VMK_KERNEL_EXPORT_TO_NAMESPACE(foo, "ns", "ver") :
+ * export foo @ns:ver
+ *
+ * VMK_KERNEL_ALIAS_TO_NAMESPACE(foo, fooAlias, "ns", "ver") :
+ * export foo as fooAlias @ns:ver
+ *
+ * Further details on the name-space/version implementation can be
+ * found in the VMKAPI module headers and documentation. The 2 second
+ * version is that if you export foo@myns:1, modules wanting access to
+ * that symbol will require an explicit
+ * VMK_MODULE_NAMESPACE_REQUIRED("myns", "1") tag to see that symbol.
