--- Comment #10 from John Baldwin <jhb@FreeBSD.org> ---
BTW, the ZFS encryption code claims that it has to the same buffer for
input/output and does a memcpy as a result.  That isn't true in 13.0 and later.
 Someone (tm) should fix ZFS to use CSP_F_SEPARATE_OUTPUT on 13.0 and later. 
Looks like it could also benefit from using CSP_F_SEPARATE_AAD as well.
