\param flags allows several flags to be specified:
\c B_USER_IO_REQUEST the buffer is assumed to be a userland buffer
and handled with special care.
\c B_ASYNC_IO_REQUEST the I/O request is to be fulfilled asynchronously.
\c B_PHYSICAL_IO_REQUEST the buffer specifies a physical rather than a
virtual address.
\param _request If successful, the location pointed to by this parameter
will contain a pointer to the created request.
