Hi,
I have a zfs send command failing for some reason...

The pool is at version 14 and all file systems are at version 3.
Ahhh... if -R is provided zfs send now calls zfs_hold_range() which later fails
in dsl_dataset_user_hold_check() as it checks if dataset is not below
SPA_VERSION_USERREFS which is defined as SPA_VERSION_18 and in my case it is 14
so it fails.
But I don't really want to upgrade to version 18 as then I won't be able to
reboot back to snv_111b (which supports up-to version 14 only). I guess if I
would use libzfs from older build it would work as keeping a user hold is not
really required...
I can understand why it was introduced I'm just unhappy that I can't do zfs
send -R -I now without upgrading a pool....
Probably no point sending the email, as I was looking at the code and dtracing
while writing it, but since I've written it I will post it. Maybe someone will
find it useful.
