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