parentCIFS: Add support for direct I/O read (diff)
CIFS: Add support for direct I/O write
With direct I/O write, user supplied buffers are pinned to the memory and data are transferred directly from user buffers to the transport layer. Change in v3: add support for kernel AIO Change in v4: Refactor common write code to __cifs_writev for direct and non-direct I/O. Retry on direct I/O failure.
