The above list of items mentioned by Josef is very important (especially w.r.t
Btrfs' subpage-blocksize support) for getting 4k blocksized filesystems to
work well for architectures like PPC64 and AARCH64 which [can] have 64k page
size. Hence I would request that these topics gets discussed during this
year's LSF/MM summit.
