Message:

SUPDrv,++: Experimental support for wrapping .r0 modules in native kernel modules on linux, so that perf and similar tools work better. Minor IOC version increase as SUP_IOCTL_LDR_OPEN now support just opening a module w/o preparing the loading. SUPDrv must export all the symbols in g_aFunctions the linux way now, or linux won't see them, so introduced a SUPR0_EXPORT_SYMBOL macro similar to RT_EXPORT_SYMBOL. bugref:9937
