That is not in this change, and no I am not taking it away. I am merely not supporting it for 8.0+ binaries. The actual system call will continue to exist and work for old binaries. However, new binaries should not use it (and in fact no binaries since 5.0 are likely using it since 5.0 and later all have separate syscalls for the various SYSV IPC methods). -- John Baldwin _______________________________________________ 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"
