I am thinking of the possiblity of backporting / porting several DragonFly and NetBSD, even OpenBSD’s features, to FreeBSD, to increase its performance, stablity, and the code readablity.

Really dislike NetBSD and OpenBSD’s commit mail style - They reveal what module is being changed, but not revelent file. Given this, you can only know “this is kernel related”, “that is doc related”, but not what exactly module they are modifying. I think I may need a script to change this.
