Similar to patch1 - if we are using a default path, then we don't want to removed even if it exists, so I *think* (but you need to confirm for me) that the following should be done: if (STREQ(monitor->path, monitor->alloc->path)) return 0; Although I wonder if a !monitor->alloc guard should be used as well. Whether it's part of a || !monitor->path return 0 or this check should be "if (monitor->alloc && STREQ(...))"... Thoughts?

I can make the changes - just let me know your preferred way to proceed... Reviewed-by: John Ferlan <jferlan@redhat.com> John [...]
