--- Comment #11 from Ronald Klop <ron...@freebsd.org> ---
The jails are not needed. It looks purely nullfs.
# zfs create zroot/data/pr-test
# cd /data/pr-test
# mkdir storage test1 test2
# mount_nullfs -o rw,noatime ./storage ./test1
# mount_nullfs -o rw,noatime ./storage ./test2
# df -h | grep "pr-test"
zroot/data/pr-test 327G 112K 327G 0% /data/pr-test
/data/pr-test/storage 327G 112K 327G 0%
/data/pr-test/test1
/data/pr-test/storage 327G 112K 327G 0%
/data/pr-test/test2
# dd if=/dev/random of=./test1/random.dd bs=1M count=1024
# df -h | grep "pr-test"
zroot/data/pr-test 327G 1.0G 326G 0% /data/pr-test
/data/pr-test/storage 327G 1.0G 326G 0%

/data/pr-test/storage 327G 1.0G 326G 0%
/data/pr-test/test2
# rm ./test2/random.dd
# df -h | grep "pr-test"
zroot/data/pr-test 327G 1.0G 326G 0% /data/pr-test
/data/pr-test/storage 327G 1.0G 326G 0%
/data/pr-test/test1
/data/pr-test/storage 327G 1.0G 326G 0%
/data/pr-test/test2
Unmount of test1 releases the blocks.
NB: mount_nullfs option nocache does not help for me.
