Like cem@ pointed out, either you expand the XOR via OR or you can also do it like this:
(((x) & CTLFLAG_MPSAFE) != 0) ^ (((x) & CTLFLAG_NEEDGIANT) != 0) which avoids having to define another macro. --HPS _______________________________________________ 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"
