Note that small allocations already *can* fail if they are done in the context of a task selected as OOM victim (i.e. TIF_MEMDIE). And yeah I've seen a case when they failed in a code that "handled" the allocation failure with a BUG_ON(!page). -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
