I think you need this patch otherwise you will be passing uninitialised data from the stack to GNTTABOP_unmap_grant_ref in fast_flush_area. Also, I think the memset of the pending_grant_handles array should happen before you start using them so I moved it to before blkif_xenbus_init. I'm not sure if this is necessary or it might possibly have to go even earlier. Signed off by Harry Butterworth butterwo@xxxxxxxxxxx
