This paragraph makes the change seem like a limited workaround for a bug in the MLX5 code. Why can't the MLX5 code be fixed instead? Looking at the patch it doesn't seem like a limitted solution at all. Now frd->frd_valid is *always* set to false. Why don't we instead just delete ->frd_valid along with the newly dead code? regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
