Description kusumi.tomohiro 2022-11-10 07:30:15 UTC 
The patch can be downloaded from here.
https://www.dragonflybsd.org/~tkusumi/diff/freebsd/hammer2/0001-Port-HAMMER2-from-DragonFly-read-only-support.patch

Since this is read-only support, I've uploaded a 4GiB image created by makefs(8).
The image contains FreeBSD 13.1-RELEASE src.
https://www.dragonflybsd.org/~tkusumi/diff/freebsd/hammer2/img/

It's probably easiest to use mdconfig(8) to mount the image.
 # mdconfig /path/to/image
 # mount_hammer2 /dev/mdX /path/to/mntpt

A false-positive lock order reversal message may appear on mounting.

There is a port sysutils/hammer2 now available.
