LGTM, thanks! And thanks for having a changelog for this dep, it helps too :)

I guess you verified if this fixes the issue, right?

[cyphar]

I verified that uid=1234,gid=5678,umask=0 (which is the most extreme example of this problem) doesn't cause errors when using MkdirAll directly.

LGTM
If there are some test cases for this issue and for "is the created directory empty" logic check, it will be more better, but I think we can add these tests in a new PR. Thanks.
