Original cover letter, updated as necessary: I'm including Peter's patch as the first one in this tiny series. (The commit description has my r-b tag in place of my Cc, and removes Jerome's Cc because he is no longer at redhat.com) The second patch is what I had in mind for a follow-up to that, when we were discussing that fix [1]. Plus, a couple more small removals that I had queued up: The third patch removes a completely unused routine: pin_user_pages_locked(). The forth patch removes a similar routine, get_user_pages_locked(), that only has one caller. It now calls get_user_pages_fast(), instead. v1 of this patchset is here: https://lore.kernel.org/all/20220131051752.447699-1-jhubbard@nvidia.com/ [1] https://lore.kernel.org/all/20220125033700.69705-1-peterx@redhat.com/ thanks, John Hubbard John Hubbard (3): mm/gup: clean up follow_pfn_pte() slightly mm/gup: remove unused pin_user_pages_locked() mm/gup: remove get_user_pages_locked() Peter Xu (1): mm: Fix invalid page pointer returned with FOLL_PIN gups include/linux/mm.h | 4 -- mm/gup.c | 100 ++++----------------------------------------- mm/mempolicy.c | 21 ++++------ 3 files changed, 16 insertions(+), 109 deletions(-) base-commit: 26291c54e111ff6ba87a164d85d4a4e134b7315c -- 2.35.1
