Sure, stack can be swapped out, but buffer passing is usually not a problem. At least, I am not aware of cases. In fact, many compat layers do exactly this, allocate the native-ABI structure on the stack, copyin the foreighn-ABI structure in pieces into the native-ABI one, and pass native to kern_foo() implementations. So I think you worries are not realized. _______________________________________________ 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"
