- * These macros provide backward-compatibility with the old

- * functions also have WARN_ON()s to let us know at runtime if
- * the get_user_pages() should have been the "remote" variant.
- *
- * These are hideous, but temporary.
- *
- * If you run into one of these __deprecated warnings, look
- * at how you are calling get_user_pages(). If you are calling
- * it with current/current->mm as the first two arguments,
- * simply remove those arguments. The behavior will be the same
- * as it is now. If you are calling it on another task, use
- * get_user_pages_remote() instead.
