Mighty upstream, I see that do_mounts_rd.c seems to make calls to sys_read and sys_lseek functions. As these are syscall functions, they expects some of the arguments to be from userspace.
I was going through the article that Greg KH wrote a while back: http://www.linuxjournal.com/article/8110?page=0,1 . I don't see any references to set_fs/get_fs under init/*. Does the memory protection get enabled only in the later stage ? Or does do_mounts_rd.c accomplish this in some other way ?
