Subject[PATCH 0/2] vfs: Report a mount r/o if the superblock is
Date
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.
