265a5cde9462d3a816b18c6cf4f0a231f1c29d1b is the first bad commit commit 265a5cde9462d3a816b18c6cf4f0a231f1c29d1b Author: Vivek Kasireddy Date: Wed Apr 10 23:59:43 2024 -0700 udmabuf: pin the pages using memfd_pin_folios() API Using memfd_pin_folios() will ensure that the pages are pinned correctly using FOLL_PIN. And, this also ensures that we don't accidentally break features such as memory hotunplug as it would not allow pinning pages in the movable zone. Using this new API also simplifies the code as we no longer have to deal with extracting individual pages from their mappings or handle shmem and hugetlb cases separately.
