:I know that zalloc() is deprecated but here is anyway a patch that
:implements zdestroy() as suggested in:
:This patch is not thread-safe and assumes that the mp lock is held
:while zalloc() and friends are called as stated in:
:I'll commit it in a few days if there are no objections.
:Regarding zalloc() lack of thread safety, I see two options:

    Looks good.

    We shouldn't worry too much about thread safety.  Only the PV entry

    I'm in no rush... it can be done as the SMP work dives into those
