167 User visible changes:
168 * mkfs.btrfs --data dup
170 People asked about duplicating data on a single device for a long time. There
171 are no technical obstacles preventing that, so it got enabled with a warning
172 about potential dangers when the device will not do the duplicated copies. See
173 mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
175 * support balance filters added/enhanced in linux 4.4
176 * usage=min..max -- enhanced to take range
177 * stripes=min..max -- new, filter by stripes for raid0/10/5/6
178 * limit=min..max -- enhanced to take range
179 Note: due to backward compatibility, the range maximum for 'usage' is not
180 inclusive as for the others, to keep the same behaviour as usage=N .
182 * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
183 * error messages updates, rewordings -- some fstests may break due to that
184 * added support for free-space-tree implementation of space cache -- this
185 requires kernel 4.5 and is not recommended for non-developers yet
