Hi, does ksmbd support direct io mode?

@maroonpu Why do you need it ? and Is it possible with samba ?

yah, my device's memory is small, causing it to swap pagecache a lot of time, so I thought I'd try it with DIO. However, after kernel_write and kernel_read are modified to implement DIO-like functions, pagecache is not generated. However, direct disk operation is too slow.
