Yes I'm fully aware of situation. I just try to make situation little 
bit better and have to start somewhere. Hopefully someone other will 
also start gain interest developing this if tools are easier to use.

I also planning to do better Xfstests support for ntfs3. Your tool at 
the moment is still only way testing it for new developers so I just 
want it to be little bit easier. I do not except you to run ntfs3. I 
also know about your previes patch. I will polish that to be usable.

I have also made ntfs3 support for Syzkaller and my patch will probably 
be merged this week. It means next week there will probably start coming 
some bug reports from there too. Local Syzkaller run against ntfs3 does 
not see very promising and there will be some bugs. But hey testing 
helps as we see how buggy things are.

Thing is that Konstantin (ntfs3 maintainer) has kept totally radio 
silence after 5.15 was released. I will make own thread about it soon as 
ntfs3 is orphan already. But that will need definitely own thread.
