I wouldn't consider it breaking, more like extending. But regardless of userspace, in the future we can also use this same interface in order to disable _built-in_ kernel modules and functionlity (e.g. 'nousb' could turn into something more canonical). This can be useful for people working in the embedded who compile module-less kernels (if module-less kernels are considered bad practicle these days, I'd like to know more). Just a thought.. One can even come up with a kernel parameter that allows a developer to skip a call to one or more of the initcall functions based on its name only even with !CONFIG_KALLSYMS (looks like that except for crypto/, almost all initcalls have unique names these days). -- Dan Aloni XIV LTD, http://www.xivstorage.com da-x (at) monatomic.org, dan (at) xiv.co.il - 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/
