eric pouech (@epo) commented about dlls/ntdll/unix/file.c:
struct file_identity id; /* directory file identity */ struct dir_data_names *names; /* directory file names */ struct dir_data_buffer *buffer; /* head of data buffers list */
- UNICODE_STRING mask; /* the mask used when creating the cache entry */
the only use of keeping that string is to avoid to flush the cache when passing rescan + the same string as the previous one... I'm not convinced it's worth it
