If attaching a PCI hostdev fails, there are several things that need to be un-done as part of the cleanup. One thing that is not done is re-calculating/re-setting the maximum amount of locked memory for the domain, since we may have changed that. Let's fix that, just to ensure everything is back the way it was. Signed-off-by: Eric Farman <farman@xxxxxxxxxxxxx> ---
Ouch. This is a bug fix that should be pushed regardless of the rest of the series, IMHO. Reviewed-by: Daniel Henrique Barboza <danielhb413@xxxxxxxxx>
