Hello!
I want to create a specific thread for each process in VM so that virtio
block requests from each process can be sumbitted in the thread related to the
process.
I tried to implement it by referring to dataplane,but I can not understand
the source about dataplane.
What should I do?

Types named *_COMMON are normally used when there's a common
parent class for multiple classes. We have only one eTSEC type,
so rename the TYPE_ETSEC_COMMON and ETSEC_COMMON macros to
TYPE_ETSEC and TYPE_ETSEC_COMMON.

When working on other things, I got confused by the etsec code,
that didn't use the TYPE_ETSEC_COMMON macro in its type
declaration, and had no subclasses despite being named
ETSEC_COMMON.
This is a very simple cleanup to remove the _COMMON suffix from
the macros, and to use the TYPE_ETSEC macro w
Instead of hardcoding the class name, use the TYPE_ETSEC macro
when registering the class and creating devices.

Hi,
Thank you for getting back!
I'm trying to follow you, but I don't understand all the details. I would like
to ask this question though:
What is the difference between v2.8.0 and this commit? With v2.8.0 the same
qemu command worked, but I admit it doesn't request sharing.
We also use libv

We should include core detail of your detailed analysis in such a
statement I think, because I it's more than just

Sorry, I think this one is more likely the cause, it's about migration:

I suspect the culprit here is [1]. I've started a git bisect between this
commit and v2.8.0 and during this time I found similar erros
"/root/qemu/nbd/server.c:nbd_receive_request():L706: read failed"
I suspect this fix tried to solve a bunch of these read fails, but broke write
requests.

not have to worry about potential overflows.
Add an assertion that our accesses to s->bat[] do not result in a buffer
overflow and that the implicit conversion performed when invoking
bat_entry_off() does not result in an int
