there are forgotten NET_ASSERT_LOCK() which are no longer valid,
in pfsync. diff below removes those which are either hit
from purge_thread() or from ioctl().
I think remaining NET_ASSERT_LOCK() should stay at least for now.
those belong to path which runs under NET_LOCK()
can you give a try diff below?
thanks and
