Btrfs subpage-blocksize feature and general filesystem topics

I have been a Btrfs contributor for a little more than 2 years. Apart from contributing some bug fix patches, I have been mostly working on getting subpage-blocksize feature (i.e. block size < page size) to work well in Btrfs.

The most recent posts of the corresponding patchset can be found at,
1. Cleanup patchset
http://article.gmane.org/gmane.comp.file-systems.btrfs/52394
2. Core patchset
http://article.gmane.org/gmane.comp.file-systems.btrfs/52408

Very recently the cleanup patchset associated with the subpage-blocksize feature has been queued for inclusion in Dave Sterba's for-next branch
(http://article.gmane.org/gmane.comp.file-systems.btrfs/52678).

I am interested in attending LSF/MM summit to mostly discuss the future direction of the subpage-blocksize patchset i.e. The core patchset currently addresses only regular I/O and also some of the features like Defrag and Extent cloning. The rest of the features like Scrubbing and Compression need to be fixed to work in subpage-blocksize scenario. I believe a face-to-face discussion with other Btrfs developers (to address some of the pain points of the patchset) would accelerate the process of inclusion of the patchset into the mainline kernel.

I am also interested in other Btrfs or general filesystem topics.
