130 User visible changes:
131 * mkfs.btrfs --data dup
133 People asked about duplicating data on a single device for a long time. There
134 are no technical obstacles preventing that, so it got enabled with a warning
135 about potential dangers when the device will not do the duplicated copies. See
136 mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
138 * support balance filters added/enhanced in linux 4.4
139 * usage=min..max -- enhanced to take range
140 * stripes=min..max -- new, filter by stripes for raid0/10/5/6
141 * limit=min..max -- enhanced to take range
142 Note: due to backward compatibility, the range maximum for 'usage' is not
143 inclusive as for the others, to keep the same behaviour as usage=N .
145 * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
146 * error messages updates, rewordings -- some fstests may break due to that
147 * added support for free-space-tree implementation of space cache -- this
148 requires kernel 4.5 and is not recommended for non-developers yet
