Michael Kerrisk 8c9a827429 mount_namespaces.7: Terminology clean-up: "mount point" ==> "mount"
Many times, this page use the terminology "mount point", where
"mount" would be better. A "mount point" is the location at which
a mount is attached. A "mount" is an association between a
filesystem and a mount point.

The correct terminology is "less privileged mount namespace"
(not "less privileged user namespace").

Michael Kerrisk ee54e5d5cc mount_namespaces.7: More clearly explain the notion of locked mounts
For a long time, this manual page has had a brief discussion of
"locked" mounts, without clearly saying what this concept is, or
why it exists. Expand the discussion with an explanation of what
locked mounts are, why mounts are locked, and some examples of the
effect of locking.

Thanks to Christian Brauner for a lot of help in understanding
these details.

Michael Kerrisk 19416046c5 mount_namespaces.7: Tweak discussion of "less privileged" mount namespace
Eric Biederman:

    I hate to nitpick, but I am going to say that when I read
    the text above the phrase "mount namespace of the process
    that created the new mount namespace" feels wrong.

    Either you use unshare(2) and the mount namespace of the
    process that created the mount namespace changes.

    Or you use clone(2) and you could argue it is the new child
    that created the mount namespace.

    Having a different mount namespace at the end of the
    creation operation feels like it makes your phrase confusing
    about what the starting mount namespace is.  I hate to use
    references that are ambiguous when things are changing.

Michael Kerrisk a0c9733194 mount_namespaces.7: Clarify description of "less privileged" mount namespaces
The current text talks about "parent mount namespaces", but there
is no such concept. As confirmed by Eric Biederman, what is mean
here is "the mount namespace this mount namespace started as a
copy of". So, this change writes up Eric's description in a more
detailed way.

If a mount point is deleted or renamed or removed in one mount
namespace, this will cause an object that is mounted at that
location in another mount namespace to be unmounted (as verified
by experiment). This was implied by the existing text, but it is
better to make this detail explicit.
