107  These routines enable/disable the pagefault handler. If disabled, it will* not take any locks and go straight to the fixup table.* User access methods will not sleep when called from a pagefault_disabled()* environment.
108  如果Architectures should provide two primitives (raw_copy_{to,from}_user())* and get rid of their private instances of copy_{to,from}_user() and* __copy_{to,from}_user{,_inatomic}().* raw_copy_{to,from}_user(to, from, size) should copy up to size bytes and则ret等于0
