Linux I/O stack design question

[Werner Fischer <devlists@xxxxxxxx>]

Dear fio users and developers,

I have a question regarding the Linux I/O stack (not directly regarding
fio, but I think fio user's and developers have a lot of knowledge
here):

I'm trying to better understand the different layers of the Linux I/O
stack and how they play together. So I have started a diagram showing
the different layers of the I/O stack:

Is this diagram correct or are there any errors in there?

Any feedback is welcome.

Thanks in advance,
Werner
