| |
By calling mount(2) with MS_REMOUNT | MS_BIND on a non-bind readonly mountpoint, it is possible to have a readonly mount without MNT_READONLY in its mnt_flags. Currently, /proc/<pid>/mountinfo and statfs will report such a mount as r/w, even though for all intents and purposes it is still readonly.
This patchset fixes show_mountinfo and statfs to report such mounts as readonly.
