As far as I see, the main use of pinfo->private_data is to pass information to
sub-dissectors. In such cases, the caller should save pinfo->private_data and
restore it after invoking all sub-dissectors it needs.
This blocks the development of MPLS ATM PW dissectors.
This patch fixes plenty of dissectors which do not follow this policy.
Most cases are trivial, except packet-rpc.c written by Uwe Girlich.
This file left unchanged.
