[Liu, Changpeng]

Hi Cathy,

Actually the code development from my side has been done for a while, include
DISCARD/WRITE ZEROES/WRITE ZEROES with Discard Bit, currently
I'm writing the specification related changes, I'll send the specification
change for review firstly.

[Qemu-devel] virtio-blk discard support

[Cathy Avery]

Hi,

I am looking at extending virtio-blk by adding support for the discard 
request.


https://lists.nongnu.org/archive/html/qemu-devel/2018-01/msg03889.html

My understanding is that you have already begun this work with [PATCH] 
virtio-blk: add DISCARD support to virtio-blk drive


https://lists.gnu.org/archive/html/qemu-devel/2017-03/msg05146.html

Are you intending to finish the implementation? I don't want to start a 
development effort if you are already working on it.


Thanks,

Cathy Avery
