Mmm this still was not the right solution as the kernel linker now linked the
variable "scsi_options" which is physically in genunix at 0xfffffffffbc8a1f0
to address 0xfffffffff3b2733b inside my driver. As mentioned, the real location
of
scsi_options is 0xfffffffffbc8a1f0
I I checked correctly, this seems to be nowhere in the kernel mappings:
BASE LIMIT SIZE NAME
