3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 97a62eaefdc196969e9d3857f65fc8a90ee1fe3c upstream.

hfsplus_readdir() incorrectly returned DT_REG for symbolic links and
special files.  Return DT_REG, DT_LNK, DT_FIFO, DT_CHR, DT_BLK, DT_SOCK,
or DT_UNKNOWN according to mode field in catalog record.  Programs
relying on information from readdir will now work correctly with HFS+.
