[PATCH v19 0/5] MR1148: ntdll: Mark created files beginning with a dot as not hidden.
Fixes bug [53826](https://bugs.winehq.org/show_bug.cgi?id=53826). -- v19: ntdll: Set xattr in NtCreateFile if inferred and requested attributes don't match. ntdll: Only infer hidden attribute from file name if xattr is not present. ntdll: Handle hidden file names inside get_file_info instead of after it. ntdll: Do not open-code hidden file handling in get_dir_data_entry. ntdll/tests: Add test for file attributes of files with names beginning with a dot. https://gitlab.winehq.org/wine/wine/-/merge_requests/1148
