This is a known pending issue. MAXCPU is used in libmemstat for internal needs only. We must get rid of this. libmemstat should get the cpu available information at runtime and use it to prepare the structures. libmemstat should not depend on MAXCPU at all. -- wbr, pluknet _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
