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