The example program can be used to discover the default
'mq_maxmsg' and 'mq_msgsize' values used to create a queue with
a mq_open(3) call in which 'attr' is NULL.

This nr_segs==0 case is no-op; the call succeeds and no
EINVAL error is returned.
See fs/splice.c vmsplice syscall which contains:
if (unlikely(nr_segs > UIO_MAXIOV))
return -EINVAL;
else if (unlikely(!nr_segs))
return 0;
And looking at the git log suggests that the code was always thus.

This and the follow-up patches will provide unification of
charset pages, minor cleanups, and some unifying cosmetic
changes. References are adjusted so that all pages include
a reference to charsets(7), which contains a description of
these sets, stray comments are removed, some obsolete
statements (like ISO 8859-1 being the de-facto ASCII
replacement) are removed, and some minor reformatting
to minimize diff's between the pages are done.
The actual substance, the character tables, remain unchanged.
This series changes the following pages (under man7): ascii,
armscii, cp1251, koi8-r, koi8-u, and all of iso_8859-*.

CP 1252 is probably one of the most used Windows Code Pages so
let's add a page for it alongside with the already provided
CP 1251 page.

This patch adds a short description about the contents of

The text "Each of these calls sets errno to an appropriate
value in the case of an error." is not only for waitid.
This patch adds a paragraph break to move the errno note
to a new paragraph where it makes sense, as it applies to
all the wait* functions.
