Re: [PATCH] kernel32: Make GetFinalPathNameByHandle warn on mounted folder.

[Zhiyi Zhang]

Hi Jeff,

It would be better if you could add some tests for this.
For example, add a test that shows the failures on wine
and then next patch fix it and remove todo_wines.

And is this for winehq bug 47787?

Thanks,
Zhiyi
