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

Hi,

This applies on top of the pin_user_pages_unlocked() patch that I sent
earlier [1].

This adds yet one more pin_user_pages*() variant, and uses that to
convert mm/frame_vector.c.

With this, along with maybe 20 or 30 other recent patches in various
trees, we are close to having the relevant gup call sites
converted--with the notable exception of the bio/block layer.
