Various pages: Remove unused <sys/types.h>
...
The manual pages are already inconsistent in which headers need
to be included. Right now, not all of the types used by a
function have their required header included in the SYNOPSIS.
If we were to add the headers required by all of the types used by
functions, the SYNOPSIS would grow too much. Not only it would
grow too much, but the information there would be less precise.
Having system_data_types(7) document each type with all the
information about required includes is much more precise, and the
info is centralized so that it's much easier to maintain.
So let's document only the include required for the function
prototype, and also the ones required for the macros needed to
call the function.
<sys/types.h> only defines types, not functions or constants, so
it doesn't belong to man[23] (function) pages at all.
I ignore if some old systems had headers that required you to
include <sys/types.h> *before* them (incomplete headers), but if
so, those implementations would be broken, and those headers
should probably provide some kind of warning. I hope this is not
the case.
[mtk: Already in 2001, POSIX.1 removed the requirement to
include <sys/types.h> for many APIs, so this patch seems
well past due.]

man2/openat2.2: Add RESOLVE_CACHED
...
RESOLVE_CACHED allows an application to attempt a cache-only open
of a file. If this isn't possible, the request will fail with
-1/EAGAIN and the caller should retry without RESOLVE_CACHED set.
This will generally happen from a different context, where a slower
open operation can be performed.

Various pages: Standardize wording around setting of 'errno' on error
...
In the RETURN VALUE sections, a number of different wordings
are used in to describe the fact that 'errno' is set on error.
There's no reason for the difference in wordings, since the same
thing is being described in each case. Switch to a standard
wording that is the same as FreeBSD and similar to the wording
used in POSIX.1.
In this change, fix some instances stating that 'errno' is set
"appropriately" to instead say "to indicate the error".

openat2.2: Improve text describing caveat for use of RESOLVE_NO_XDEV
...
From email discussions with Aleksa Sarai:
> .\" FIXME I find the "previously-functional systems" in the previous
> .\" sentence a little odd (since openat2() ia new sysycall), so I would
> .\" like to clarify a little...
> .\" Are you referring to the scenario where someone might take an

> .\" If I'm not on the right track, could you point me in the right

This is mostly meant as a warning to hopefully avoid applications
because the developer didn't realise that system paths may contain
symlinks or bind-mounts. For an application which has switched to
openat2() and then uses RESOLVE_NO_SYMLINKS for a non-security reason,
it's possible that on some distributions (or future versions of a
distribution) that their application will stop working because a system
path suddenly contains a symlink or is a bind-mount.
This was a concern which was brought up on LWN some time ago. If you can
think of a phrasing that makes this more clear, I'd appreciate it.

openat2.2: Document new openat2(2) syscall
...
Rather than trying to merge the new syscall documentation into
open.2 (which would probably result in the man-page being
incomprehensible), instead the new syscall gets its own dedicated
page with links between open(2) and openat2(2) to avoid
duplicating information such as the list of O_* flags or common
errors.
In addition to describing all of the key flags, information about
the extensibility design is provided so that users can better
understand why they need to pass sizeof(struct open_how) and how
their programs will work across kernels. After some discussions
with David Laight, I also included explicit instructions to zero
the structure to avoid issues when recompiling with new headers.
