> Subject: [PATCH v2] raw/ntb: add check for disabling interrupt in dev close
> ops
>
> During EAL cleanup stage, all bus devices are cleaned up properly.
> In the meantime, the ntb example app will also do the device cleanup
> process, which may call the dev ops '*dev->dev_ops->dev_close' twice.
>
> If this dev ops for ntb was called twice, the interrupt handle for
> EAL will be disabled twice and will lead to error for the seconde
> time. Like this: "EAL: Error disabling MSI-X interrupts for fd xx"
>
> Thus, this patch added the check process for disabling interrupt in
> dev_close ops, to ensure that interrupt only be disabled once.
