This patch is used to dispense trace info when system boots with debug
kernel. I have verified it on RHEL6.2& SLES11.2. Both work fine.
In the failure case, system logs that:
/Feb 21 19:33:55 nsgbj-216-137 kernel: sysctl_check_dir: failed: /dev ref: /dev .7
.....
These lines were removed in November 2009 by Eric Biederman in
commit 894d2491153a9f8270dbed21175d06fde4eba6c7
So I'm not keen on adding them back without understanding the history.
Eric: Do we need these after all?
For the main trunk no. The .ctl_name field no longer exists.
kernel/binary_sysctl.c is used to provide backwards compatibility with
the old binary names.
There might be a point for doing something in -stable or someone's
enterprise kernel if some messed up set of backports were merged.

Thanks for the quick response Eric!!
Qing: It looks like this is not an issue in mainline.
If you want to get something fixed in SLES or RHEL, I suggest you log an
issue in the relevant bugzillas (though I just checked SLES11-SP2, and
it doesn't mention sysctl_check_dir at all).
