- * get_user_pages_remote() was added by commit 1e9877902dc7
- * ("mm/gup: Introduce get_user_pages_remote()") in v4.6 (2016-02-12).
- *
- * The very next commit cde70140fed8 ("mm/gup: Overload get_user_pages()
- * functions") 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 if this API has tsk argument) 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.
- *
- * get_user_pages_remote() write/force parameters were replaced
- * with gup_flags by commit 9beae1ea8930 ("mm: replace get_user_pages_remote()
- * write/force parameters with gup_flags") in v4.9 (2016-10-13).
- *
- * get_user_pages_remote() added 'locked' parameter by commit 5b56d49fc31d
- * ("mm: add locked parameter to get_user_pages_remote()") in
- * v4.10 (2016-12-14).
- *
- * get_user_pages_remote() removed 'tsk' parameter by
- * commit 64019a2e467a ("mm/gup: remove task_struct pointer for
- * all gup code") in v5.9-rc1 (2020-08-11).
