The 64 bit piece works fine here and I used it for debugging the vmalloc work. Not sure about the 32 bit piece. > A pacth which I created is attached, I've successfully tested it by this > module: Great! Someone else picks this up.

We could use include/linux/bounds.h to make VMALLOC_START/VMALLOC_END (or whatever you need for checking the memory boundaries) a cpp constant which may allow the use in page_32.h without circular dependencies. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
