[libvirt] [PATCH RFC 0/4]] nwfilter: don't reinstantiate filters if they are not changed

[Nikolay Shirokovskiy]

The series adds optimization in network filters instantiation as suggested
in [1]. Applied on top of [2].

However this approach has drawback I'm unfortunately discovered too late)
Next steps will left us with no network filters after this series applied:

systemctl stop libvirtd
systemctl restart firewalld
systemctl start libvirtd

In case of system update libvirt binaries ctime will change and filters will be
reinstalled.

Nikolay Shirokovskiy (4):
  nwfilter: add nwfilter hash
  nwfilter: don't reinstantiate filters if they are not changed
  nwfilter: force filters reinstantiation on firewalld reload
  nwfilter: force filters reinstantiation on binary update
