Michael Kerrisk 41976bc5f3 mount.2: Mandatory locking also now requires CONFIG_MANDATORY_FILE_LOCKING
This is so since Linux 4.5. See the definition of may_mandlock()
in fs/namespace.c.

As far as I can tell, these EBUSY errors disappeared
with the addition of stackable mounts in Linux 2.4.

Michael Kerrisk 050f349421 mount.2: ERRORS: add EBUSY for the case of trying to stack same mount twice
It is not possible to consecutively stack mounts of the
same source+target inside the same mount namespace.

For example, if procfs was already mounted against /proc in
this mount namespace:

    $ sudo mount -t proc none /proc
    mount: /proc: none already mounted or mount point busy.

See the following code in fs/namespace.c:

        /* Refuse the same filesystem on the same mount point */
        err = -EBUSY;
        if (path->mnt->mnt_sb == newmnt->mnt.mnt_sb &&
            path->mnt->mnt_root == path->dentry)
                goto unlock;

Keno Fischer 360d745544 mount.2: Add EINVAL error condition when MS_BINDing MNT_LOCKED submounts
When the user creates an unprivileged mount namespace, the Linux
kernel sets the MNT_LOCKED flag [1] on any submounts to prevent
such mounts from being unmounted inside the mount namespace. Such
an unmount would reveal the filesystem tree behind the mount,
which is not otherwise possible from an unprivileged vantage
point.

Attempting to unmount such a mount will fail with EINVAL. However,
less obvious implication is that attempting a bind mount without
MS_REC, where the tree being bound contains locked sub-mounts,
will also fail with EINVAL, because, without MS_REC, such
submounts are effectively being unmounted.

Cursory googling shows several instances of people running into
this problem, so I felt it advantageous to have it documented in
the man page.

NeilBrown c84a877924 mount.2: Revise description of MS_REMOUNT | MS_BIND
MS_REMOUNT|MS_BIND affect all per-mount-point
flag.  MS_RDONLY is only special because it,
uniquely, is both a per-mount-point flag *and* a
per-filesystem flag.

So the sections of per-mount-point flags and
MS_REMOUNT can usefully be clarified.

Michael Kerrisk f429fadc96 mount.2: Restructure discussion of 'mountflags' into functional groups
The existing text makes no differentiation between different
"classes" of mount flags. However, certain flags such as
MS_REMOUNT, MS_BIND, MS_MOVE, etc. determine the general
type of operation that mount() performs. Furthermore, the
choice of which class of operation to perform is performed in
a certain order, and that order is significant if multiple
flags are specified. Restructure and extend the text to
reflect these details.
