Re: Modules with list

[Adam J. Richter]

	I wrote two really buggy examples in my previous reply
to Kai.  First of all, here is a more "correct" version of
vmlinux.lds.S for determining the disposition of devexit at
kernel load time, although I don't know if ld will allow it:

Also here is a "corrected" bit of untested code for clearing
devexit references at module load time:

        if (!module->removable) {
                void ***pptr = module->devexit_p_start;
                while (pptr != module->devexit_p_end) {
                        **pptr = NULL;
                        pptr++;
                }
        }

Sorry for responding too hastily before.
