[PATCH v2 0/3] MR5737: Draft: kernelbase: Use ERROR_DIRECTORY for FindFirstFileExW on invalid name.
When `FindFirstFileA` is called with `<path>/<file>/*` (where file is expected to be a directory), Windows uses the `ERROR_DIRECTORY` error.
This patch changes Wine's implementation to match Windows. This fixes a crash in Unity of Command II.
-- v2: server: Don't return STATUS_OBJECT_NAME_INVALID on ENOTDIR. ntdll/tests: Test error code when NtOpenFile uses file as directory.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=145902
