Brian Atkinson d67eb17e27 Use pin_user_pages API for Direct I/O requests ... As of kernel v5.8, pin_user_pages* interfaced were introduced. These interfaces use the FOLL_PIN flag. This is preferred interface now for Direct I/O requests in the kernel. The reasoning for using this new interface for Direct I/O requests is explained in the kernel documenetation: Documentation/core-api/pin_user_pages.rst If pin_user_pages_unlocked is available, the all Direct I/O requests will use this new API to stay uptodate with the kernel API requirements.
