Subject: read only bind mount ignores ready only

It seems that the kernel has a bug where it silently ignores the
MS_RDONLY flag when creating a bind mount. mount issues a warning
that the mount point appears to be read-write even though you
requested read only. The reporter suggests a patch to automatically
attempt to remount with MS_RDONLY before issuing this warning to work
around the kernel bug. What do you think?
