Cause:
Compiling with -E shows:
__setup("scsi_logging=", scsi_logging_setup);
i.e. __setup has not been recognized as a macro.
Fix: (I think!)
My understanding of this __init stuff in init.h is that it is hints
for files built in and is to be ignored in modules. Most of the
macros have dummy definitions if MODULE is defined.
I made this change and scsi.c now compiles:
bash-2.01$ diff -c init.h.orig init.h
