Ok, so you claim that ARCH_KMALLOC_MINALIGN is not set on some architectures, and thus SLOB does the wrong thing. Doesn't that rather obviously mean that the affected architectures should define ARCH_KMALLOC_MINALIGN? Because, well, they have an "architecture-specific minimum kmalloc alignment"? This change will regress SLOB everywhere where '4' was the right answer. -- Mathematics is the supreme nostalgia of our time. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
