This patch set introduces functionality into btrfsctl and mkfs.btrfs to support the kernel patches for hot data tracking and migration to SSD with Btrfs. New functionality includes a -h option to mkfs.btrfs to preallocate approrpiate block group types for SSD data migration, and also includes additional options for btrfsctl to interact with the new ioctls introduced by the kernel patches.
