I only did this to make it more feasible to remove the tid argument from primitives which I may or may not end up doing, undecided yet. As for changing the conditon to testing a global, I don't think this change affects feasibilitly. It onlly requires some more churn by hand which I'm happy to do if said change is implemented. -- Mateusz Guzik <mjguzik gmail.com> _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
