Looks like the issue is already fixed in VFS (see discussion):
http://thread.gmane.org/gmane.linux.kernel.cifs/2284
Jeff: Looks like the issue is reproducible with 2.6.37 too.. Any idea
which is the commit that fixes this problem and whether it has been
marked for -stable?

So Jeff's change referenced (to fs/cifs/dir.c) above is not needed due
to a vfs change?

Yes. He asked to ignore his patch here:

Sorry it was not a VFS fix but a fix from Al Viro that fixed this
problem. IIUC, the commit has made it to cifs-2.6.git but not upstream.

It is in the mainline. And there's no way anybody could've seen such
trace on .37 or earlier, since d_set_d_op() didn't exist before that.
