My point however is that the API should say that the driver has been audited, not that the mapping has been done in some special way. For example the mapping can be in some kind of wrapper, not directly in the driver. However you want the driver validated, not the wrapper. Here's an idea: diff --git a/include/linux/audited.h b/include/linux/audited.h new file mode 100644 index 000000000000..e23fd6ad50db --- /dev/null +++ b/include/linux/audited.h @@ -0,0 +1,3 @@ +#ifndef AUDITED_MODULE +#define AUDITED_MODULE +#endif Now any audited driver must do #include <linux/audited.h> first of all. Implementation-wise it can do any number of things, e.g. if you like then sure you can do: #ifdef AUDITED_MODULE #define pci_ioremap pci_ioremap_shared #else #define pci_ioremap pci_ioremap #endif but you can also thinkably do something like (won't work, but just to give you the idea): #ifdef AUDITED_MODULE #define __init __init #else #define __init #endif or any number of hacks like this. -- MST _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
