8 characters is enough for showing most commits unambiguously.
12 would be necessary if we didn't have the date. However, the date can
be used to disambiguate a commit better than a longer hash. Let's cut
some characters to make commit references more readable.

mincore(2) was implemented in FreeBSD on 1995-10-21,[1] and was first
included in the FreeBSD 2.2 release on 1997-03.[2]
It was implemented in NetBSD on 1999-06-15,[3] and was first included in
the NetBSD 1.5 release on 2000-12-06,[4] (despite the commit message
stating its intended inclusion in NetBSD 1.4.1).
It was implemented in OpenBSD on 2001-03-09,[5] and was first included
in the OpenBSD 2.9 release on 2001-06-01.[6]
All other listed systems are taken at face value and rearranged in

'for (;;)' is the most common spelling:
$ grep -rn 'while (true)' man/
$ grep -rn 'while (1)' man/ | wc -l

$ grep -rn 'for (;;)' man/ | wc -l

I also personally happen to like it most, mentally reading it as
'for ever'.

SEEK_DATA and SEEK_HOLE appeared in Solaris no later than 2005-12-12,
when a ZFS developer stated in a blog post that "[a]t this [time of]
writing, SEEK_HOLE and SEEK_DATA are Solaris-specific."[1] The release
notes for Solaris 10 are dated to 2005-12.[2] So the constants were
likely added in Solaris 10.
They were added to FreeBSD on 2007-04-05,[3] before being released in
FreeBSD 7.0 - the release notes stating that "[s]upport for Sun's ZFS
has been added" for amd64, i386, and pc98.[4]
They were also added to DragonFly BSD on 2009-04-07,[5] before being
released in DragonFly BSD 2.3.1 (which strangely seems to have no
release notes).[6]
The commit adding the constants to DragonFly BSD states that the commit
contents were obtained from FreeBSD.[5] So chronologically FreeBSD is
listed before DragonFly BSD. And the commit adding them to FreeBSD
references their implementation in OpenSolaris.[3] So chronologically
Solaris is listed before FreeBSD.
POSIX.1-2024 is also moved to the end of the list, since it was released
decades after any system discussed here.

glibc 2.4 released on 2006-03-06.[1] Linux 2.6.16 released on
2006-03-20.[2] So chronologically list glibc before Linux.
POSIX.1-2008 released in 2008 (shocker!). However, glibc's addition of
linkat(2) on 2005-12-16 declared the function in posix/unistd.h,[3]
implying it was known (or at least suspected) to have been proposed for
inclusion in POSIX.1-2008.[4] So chronologically list POSIX before
glibc.

Some authors have given express permission for the transformation done
in that old commit, and their notices remain transformed. But those
that didn't give express permission have their copyright notices
restored now.
It's unclear whether the transformation was legally valid. I believe it
was, but since IANAL, and just to be cautious, we've agreed to restore
them.
This restoration, at least, unifies the formatting, to reduce entropy.

access right
Move the description of the LANDLOCK_ACCESS_FS_IOCTL_DEV access right
together with the file access rights.
This group of access rights applies to files (in this case device
files), and they can be added to file or directory inodes using
landlock_add_rule(2). The check for that works the same for all file
access rights, including LANDLOCK_ACCESS_FS_IOCTL_DEV.
Invoking ioctl(2) on directory FDs can not currently be restricted
with Landlock. Having it grouped separately in the documentation is a
remnant from earlier revisions of the LANDLOCK_ACCESS_FS_IOCTL_DEV
patch set.
The same change was also done in kernel documentation, linked below.
Fixes: 893db5f60c73 (2024-08-21; "landlock.7: Document Landlock ABI version 5 (IOCTL)")

[U]INTPTR_MAX and INTPTR_MIN
INTPTR_MAX, UINTPTR_MAX, and INTPTR_MIN are defined if and only if
intptr_t(3type) and uintptr_t(3type) are declared.[1] So given that the
types are only mandatory on XSI-conformant systems, the same is true for
the macros.
