This particular scenario was easily reproduced using a NFS export. When the

vflush() had flushed references on the filesystem's root vnode, which in
turn caused its v_interlock to be destroyed. The next time 'zfs unmount'

Since vflush() on FreeBSD is a definitive call, there is no need to check

date: 2010/02/04 14:10:12; author: sthen; state: Exp; lines: +24 -19;
pf_get_sport() picks a random port from the port range specified in a
nat rule. It should check to see if it's in-use (i.e. matches an existing
PF state), if it is, it cycles sequentially through other ports until
it finds a free one. However the check was being done with the state
keys the wrong way round so it was never actually finding the state
to be in-use.
- switch the keys to correct this, avoiding random state collisions
with nat. Fixes PR 6300 and problems reported by robert@ and viq.
- check pf_get_sport() return code in pf_test(); if port allocation
fails the packet should be dropped rather than sent out untranslated.
Help/ok claudio@.

- We also need to bzero() the key to zero padding, otherwise key
won't match.
- Collapse two if blocks into one with ||, since both conditions
