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
