That's only true for the current implementation of the page allocator. If we were to change the page allocator behaviour to not do that (and we change it daily!) then all those callsites which wanted __GFP_REPEAT behaviour will get broken. So someone would need to go back and work out how to unbreak them, if we remembered. Plus there's presumably some documentary benefit in leaving the __GFP_REPEATs in there. Why are those __GFP_REPEATs present at those callsites? What were developers trying to achieve? -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
