The NR_QUICK thing seems a bit backwards anyways, perhaps it would make more sense to have architectures set CONFIG_GENERIC_QUICKLIST in the same way that the other GENERIC_xxx bits are defined, and then set NR_QUICK based off of that. It's obviously going to be 2 or 1 for most people, and x86 seems to be the only one that needs 2. How about this? -- diff --git a/mm/Kconfig b/mm/Kconfig index 7942b33..2f20860 100644 --- a/mm/Kconfig +++ b/mm/Kconfig @@ -163,3 +163,8 @@ config ZONE_DMA_FLAG default "0" if !ZONE_DMA default "1" +config NR_QUICK + int + depends on GENERIC_QUICKLIST + default "2" if X86 + default "1" - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
