iscsi/libiscsi and discards works fine since your latest patches:
1bd075f29ea6d11853475c7c42734595720c3ac6
cfb3f5064af2d2e29c976e292c9472dfe9d61e31
27cbd828c617944c0f9603763fdf4fa87e7ad923
b20909195745c34a819aed14ae996b60ab0f591f

But in rbd it starts to cancel the discard requests. Both using the same 
guest and host kernel with the same QEMU version.

Greets,
