Hello,
I'm going to look at fixing some of the performance issues that crop up because
of our reservation system. Before I go and do a whole lot of work I want some
feedback. I've done a brain dump here
https://btrfs.wiki.kernel.org/index.php/ENOSPC
This has an explanation of how our reservation system currently works and the
problems I think there are with it, and the solutions I'm going to try. If
somebody has any better ideas please put them on that page along with your IRC
nick so I can find you and we can chat about your idea. Once we have a few
things we all agree on I'll start hammering away at them. Some of these things
I'm going to go ahead and do because they are just correct, but the bigger
things such as the flusher thread I'd like some more input on. Any crazy ideas
welcome, but if your idea involves completely scrapping the current system it
will have to be an awesome idea since I don't really want to spend the next year
fixing early enospc problems again. Thanks,
Josef
