Yes, unfortunately, reiserfs does not support entry types.
Probably it should, but there is nothing wrong to not support it:
man readdir:
According to POSIX, the dirent structure contains a field char d_name[]
of unspecified size, with at most NAME_MAX charac╜
ters preceding the terminating null character. Use of other fields
will harm the portability of your programs. POSIX
1003.1-2001 also documents the field ino_t d_ino as an XSI extension.
