Brian Atkinson 882a809983 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.
