I bet you and I could have some very interesting discussions about how to implement robust tx undo in a filesystem.

I'm curious to hear about this topic, because I look at rust, and I look at supercomplex filesystem code and wonder how in the world we're ever going to port a (VERY SIMPLE) filesystem to Rust. Now that I'm nearly done with online repair for XFS, there's a lot of stupid crap about C that I would like to start worrying about less because some other language added enough guard rails to avoid the stupid. > - lots more bug squashing, scalability work, debug tooling improvements > > I'd like to talk more about where things are at, long term goals, and > finally upstreaming this beast. Go for it, I say. --D
