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

man/man2/lseek.2: HISTORY: Update appearances of SEEK_{DATA,HOLE}
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.
