52 # This program use several vectors for writev(), the kernel goes over them
53 # one at a time, copying them from userspace, getting the user data ready
54 # for IO. If it takes a page fault while iterating over the vectors in the
55 # IOV, it stops, and sends what it got so far. We try to find a bug at this
