If there's a module anywhere which calls swiotlb_init() then I suspect it's one which deserves breaking ;) I'll remove the export. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

A 'git grep swiotlb_init' showed no users in drivers/ so maybe the EXPORT_SYMBOL can be deleted which would cure the warning? I took the pragmatic approach and made it non-__init.
