Bart Van Assche d84fc0783d vdisk_fileio: Add support for asynchronous I/O processing 
Using asynchronous has the advantage that SCSI commands can be processed
concurrently even if only one SCST command thread has been configured.
Asynchronous direct I/O has the additional advantage that the page cache
is bypassed and hence that the command processing overhead is reduced.

Asynchronous I/O is not used when DIF is enabled because it is
nontrivial to ensure that a DIF read received after a DIF write
returns the data that has just been written.
