I still need to decide which specific topic to bring/promote, but I'd certainly

Generally would like to talk about...
Trim/discard plans in filesystem - lately I'm thinking a batch mechanism may
be better than trim-as-you-go.
Advancements in generic test infrastructures since last year.
Could talk a bit about the advancements in proper alignment detection&
setup for storage& filesystems but that's not a very big topic.
Jan's suggestion of some writeback sanity sounds good to me too.
Thanks,

I think that all of the above are great topics for this time around.
Specifically, the alignment work has been interesting in that we have
tried to get not just the kernel bits but the entire stack to work
properly.
Both this and the discard work should still be quite topical if we can
get the various storage vendors to evaluate our current upstream bits
in time :-)
As you know, I've been picking away at the discard support from the file
system all the way down to the storage. I think I should have some good
numbers and guidance come time for the workshop.
I am also interested in discussing all things I/O scheduler.
Oh, and I'd like to attend as well. ;)

One topic that I think that might be interesting is to talk about how
well we did integrating all of these new features into the stack that
cross IO/FS/scheduler boundaries. In a way, we got ahead of the hardware
vendors with both the discard support and the various topology bits but
did manage to get that supported not just in the kernel but up the tool
chain as well.
Might be interesting to see where we ended up, think about next steps
and if/how we would improve on what we have....
