When I took a quick glance at this briefly yesterday one of the things that crossed my mind was exporting the different netif/node/port flush functions and grouping the callbacks into a single callback that calls each of the flush functions and then synchronize_net() once at the end; similar to what you describe above. Perhaps that is the best solution upstream. Unless someone else wants to develop/test a patch, I'll put one together. -- paul moore www.paul-moore.com _______________________________________________ Selinux mailing list Selinux@xxxxxxxxxxxxx To unsubscribe, send email to Selinux-leave@xxxxxxxxxxxxx.
