We would try to be clever and compare the *data instead of the *elt.
Somethink like this might be of more general use:
/* Unlink arbitrary element from the list that contains data */
void llist_unlink_data(llist_t **head, void *data)
{
llist_t *elt;
for (elt = *head; elt; elt = elt->link) {
if (elt->data == data) {
llist_unlink(elt);
return;
}
}
}

combination of linux not providing a useable linux/module.h to userspace and
mixing legacy-cruft with the current stuff in one insmod.c.

No obj-code changes.

modules out there that are half a megabyte! mmap()ing is way nicer
for small mem boxes.

The patch makes the order of the alias/blacklist in modprobe.conf
irrelevant (like module-utils' modprobe). In first patch the alias had
to be defined before the blacklist which caused problems because the
modprobe.conf file is read before /lib/modules/*/modules.alias.
The attatched patch will mark the blacklisted module itself rather than
trying to find the alias that points to the blacklisted module and test
this flag later in the alias resolving stage.
