Both an official PkgBase install and a personal build do not find the =
new oid for this for main:
# uname -apKU
FreeBSD 7950X3D-ZFS 15.0-CURRENT FreeBSD 15.0-CURRENT =
main-n268827-75464941dc17 GENERIC-NODEBUG amd64 amd64 1500015 1500015
# uname -apKU
FreeBSD 7950X3D-ZFS 15.0-CURRENT FreeBSD 15.0-CURRENT #139 =
main-n268827-75464941dc17-dirty: Sun Mar 17 03:16:30 UTC 2024 =

The results are:

Note: The mount_nullfs man page does have:
QUOTE
cache Force enable metadata caching.
The vfs.nullfs.cache_vnodes sysctl specifies global default for =
mount-
specific cache/nocache option.
END QUOTE
That is evidence of the vintage of materials.
