Here are a few topic ideas:

(1)  The first topic that might span IO & FS tracks (or just pull in device 
mapper people to an FS track) could be adding new commands that would allow 
users to grow/shrink/etc file systems in a generic way.  The thought I had was 
that we have a reasonable model that we could reuse for these new commands like 
mount and mount.fs or fsck and fsck.fs. With btrfs coming down the road, it 
could be nice to identify exactly what common operations users want to do and 
agree on how to implement them. Alasdair pointed out in the upstream thread that 
we had a prototype here in fsadm.

(2) Very high speed, low latency SSD devices and testing. Have we settled on the 
need for these devices to all have block level drivers? For S-ATA or SAS 
devices, are there known performance issues that require enhancements in 
somewhere in the stack?

(3) The union mount versus overlayfs debate - pros and cons. What each do well, 
what needs doing. Do we want/need both upstream? (Maybe this can get 10 minutes 
in Al's VFS session?)

Thanks!
