 As deep as possible.  
I'm need to implement (in pure C of course, not in BLISS :-) )  a logic for atomic write for 4k block on several physical devices (with 512 bytes granularity) in Soft. Def. Stor. project. 
In a couple words:  I/O request for 4k block should be spread over 4-8 disks as "atomic" action.
There is "start TX" phase - and "end TX" phase. My driver accept an I/O request for the particular block and wait for "end TX" signal.

Thanks a lot for answer.
