+/*  get_user_pages_remote() was added by:
+ *    2016 Feb 12: 1e9877902dc7e11d2be038371c6fbf2dfcd469d7
+ *
+ *  The very next commit (cde70140fed8429acf7a14e2e2cbd3e329036653)
+ *  deprecated the 8-argument version of get_user_pages for the
+ *  non-remote case (calling get_user_pages with current and current->mm).
+ *
+ *  The guidelines are: call NV_GET_USER_PAGES_REMOTE if you need the 8-argument
+ *  version that uses something other than current and current->mm. Use
+ *  NV_GET_USER_PAGES if you are refering to current and current->mm.
+ *
+*  Note that get_user_pages_remote() requires the caller to hold a reference on
+*  the task_struct (if non-NULL) and the mm_struct. This will always be true
+*  when using current and current->mm. If the kernel passes the driver a vma
+*  via driver callback, the kernel holds a reference on vma->vm_mm over that
+*  callback.
