Subject: [PATCH v2 0/2] mm/gup: introduce pin_user_pages_locked(), use it in frame_vector.c

Hi,

Changes since v1:

* added an assert-and-return to the corresponding
get_user_pages_locked() call, to keep out any externally set FOLL_PIN flag,
thanks to Souptick Joarder's review for spotting that.

* Added Acked-by and Reviewed by tags from David and Pakaj

  mm/gup: introduce pin_user_pages_locked()
  mm/gup: frame_vector: convert get_user_pages() --> pin_user_pages()
