--data dup People asked about duplicating data on a single device for a long time.

See mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE. * support balance filters added/enhanced in linux 4.4 * usage=min..max -- enhanced to take range * stripes=min..max -- new, filter by stripes for raid0/10/5/6 * limit=min..max -- enhanced to take range Note: due to backward compatibility, the range maximum for 'usage' is not inclusive as for the others, to keep the same behaviour as usage=N . * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance) * error messages updates, rewordings -- some fstests may break due to that * added support for free-space-tree implementation of
