Because of the issues related to fracturing large pages, you might have had to go this route eventually anyway. Changing the kernel linear map isn't nice. FWIW, you could test this scheme by just converting all the users to vmalloc() and seeing what breaks. They'd all end up rounding up all their allocations to PAGE_SIZE, but that'd be fine for testing. Could you point out 5 or 10 places in the kernel that you want to convert? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
