Patch 1 isn't a workaround, which is needed for stable tree, and the other fixes won't work without patch 1. However, we may revert patch 1 for 5.1 in which multi-page bvec is supported. I am fine to merge the last three in one patch since the backporting isn't too hard for me, :-) However I guess our stable guys may prefer to simpler fix. Thanks, Ming Lei
