2.6.17-rc3 - fs/namespace.c issue

There seems to have been a bug introduced in this changeset:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f6422f17d3a480f21917a3895e2a46b968f56a08

Am running 2.6.17-rc3-mm1. When this changeset is applied, 'mount --bind'
misbehaves:

> # mkdir /foo
> # mount -t tmpfs -o rw,nosuid,nodev,noexec,noatime,nodiratime none /foo
> # mkdir /foo/bar
> # mount --bind /foo/bar /foo
> # tail -2 /proc/mounts
> none /foo tmpfs rw,nosuid,nodev,noexec,noatime,nodiratime 0 0
> none /foo tmpfs rw 0 0

Reverting this changeset causes both mounts to have the same options.

(Thanks to Stephen Smalley for tracking down the changeset...)
