--- Comment #7 from John Baldwin <jhb@FreeBSD.org> ---
(In reply to Alexandre martins from comment #5)
Well, hmm.  If the uio is in the csession than perhaps we should just forma=
lize
"only one op at a time" by having the crypto ioctls detect that case and ei=
ther
fail or block.  Alternatively we could move the uio into the 'cod'.  Probab=
ly
it is simpler to just enforce "one op at a time" and then your original pat=
ch
should work I think.
