Re: [Qemu-devel] scsi-hd with discard_granularity and unmap results in Aborted Commands

Hi Paolo,
Hi Josh,

i started to port the iscsi fixes to rbd. The one think i'm missing is. 
How to tell / call rbd to cancel I/O on the server side?

I grepped librbd source code for abort / cancel but didn't find anything.

Qemu must be able to tell rbd to cancel a specific I/O request.

Greets,
Stefan
