Hi, Here is a v2 that includes a small change that follows from Souptick's review of another very similar patchset (that added pin_user_pages_locked()) [1]. This applies on top of today's linux.git (5.7-rc7+). Changes since v1: added an assert-and-return to the corresponding get_user_pages_unlocked() call, to keep out any externally set FOLL_PIN flag. These patches are getting merged via Andrew's linux-mm tree, due to adding a new pin_user_pages*() variant to gup.c. However, it would be nice if anyone from IVTV or linux-media could provide some run time testing, maybe even a Tested-by. I've run this patchset through non-destructive xfstests, and a few other things such as LTP. However, I'm not set up for IVTV specific testing.
