    4 Subject: [PATCH 1/1] UBUNTU: SAUCE: Created MODULE_EXPORT/MODULE_IMPORT macros
    5
    6 BugLink: http://bugs.launchpad.net/bugs/430694
    7
    8 Create a macro pair that can be used to symbolicly link two modules
    9 if they are not already directly linked.
    10 This relationship uses the facilities of depmod and modprobe to
    11 get soft dependencies loaded in the correct order.
    12
    13 Examples of soft dependencies are:
    14 1) i915 and intel_agp (agp _must_ be loaded before i915)
    15 2) any net driver that uses phylib modules.
