[Qemu-devel] [PATCH 43/51] scsi: Assign cancel_io vector for scsi_disk_emulate_ops

[Michael Roth <mdroth@linux.vnet.ibm.com>]

From: Paolo Bonzini <pbonzini@redhat.com>

Some emulated disk operations (MODE SELECT, UNMAP, WRITE SAME)
can trigger asynchronous I/Os.  Provide the cancel_io callback
to ensure that AIOCBs are properly cleaned up.
