This logic can be repeated, but it is probably too much for the purpose. It would be enough to have single frame (we cannot reuse CMAP1), protected by a spin mutex. I do not see much sense in providing optimized per-cpu frames for this case. _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
