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
