question about sharedsubtree.rst

[Julia Lawall]

Hello,

Documentation/filesystems/sharedsubtree.rst contains the following:

        ->mnt_flags
	        takes two more flags to indicate the propagation status of
	        the vfsmount.  MNT_SHARE indicates that the vfsmount is a shared
	        vfsmount.  MNT_UNCLONABLE indicates that the vfsmount cannot be
		replicated.

I guess that MNT_SHARE should be MNT_SHARED.  More seriously,
MNT_UNCLONABLE seems to have never existed, except in a patch proposed in
2005: https://lists.linuxcoding.com/kernel/2005-q3/msg01881.html
Should there be a description of MNT_UNBINDABLE instead?  Or something
else?

thanks,
julia
