Probleam reading fdinfo symlinks after30a08bf2d31d275c6fc71dd1811342777e95c831

Hi Linus,

just tried 3.5-rc1 out and found that with commit
30a08bf2d31d275c6fc71dd1811342777e95c831 the reading
of fdinfo files returns "Too many levels of symbolic links"
error.

 | [root@neptune~]# cat /proc/`pidof crond`/fdinfo/0
 | cat: /proc/1417/fdinfo/0: Too many levels of symbolic links

so I reverted it manually and now it works as expected

 | [root@neptune ~]# cat /proc/`pidof crond`/fdinfo/0
 | pos:	0
 | flags:	0100002

I suspect this is unintentional behaviour of the commit.
