Michael Kerrisk bf4f7a7867 exit_group.2: Remove a confusing reference to _exit(2) in DESCRIPTION 
As noted by Jakub:

    BTW, the exit_group.2 man page could use an update (possibly
    by merging it into exit.2): it says that the "system
    call is is equivalent to _exit(2) except that it terminates
    not only the calling thread, but all threads in the calling
    process's thread group", which isn't helpful these days.

Alejandro Colomar fb74563941 getaddrinfo.3: Note that 'errno' is set in parallel with EAI_SYSTEM 
The previous wording wasn't very explicit, leaving room for
believing that 'errno' may be 0 after returning EAI_SYSTEM.

Use a wording similar to other pages, for added consistency.

[mtk: edited commit message title; also, POSIX notes that
'errno' is set in this case.]

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.

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.
