The earlier patchset posted by Chandra Seethraman was to get 4k blocksize to work with ppc64's 64k PAGE_SIZE. I chose to do 2k blocksize on x86_64's 4k PAGE_SIZE since that would allow others in the community to work/experiment with subpagesize-blocksize feature. The root node of "tree root" tree has 1957 bytes being written by make_btrfs() (in btrfs-progs). Hence I chose to do 2k blocksize for the initial subpagesize-blocksize work. So with this patchset the supported blocksizes would be in the range 2k-64k.
