This change can be detected via the new #defines, and I plan to add similar changes in the near future (see the hackers@ mail about this patch; some of them cannot be detected via the preprocessor or even at compile time). Therefore, I think a __FreeBSD_version bump is not yet appropriate. -- Jilles Tjoelker _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
