59 * mkfs.btrfs --data dup
61 People asked about duplicating data on a single device for a long time. There
62 are no technical obstacles preventing that, so it got enabled with a warning
63 about potential dangers when the device will not do the duplicated copies. See
64 mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
66 * support balance filters added/enhanced in linux 4.4
67 * usage=min..max -- enhanced to take range
68 * stripes=min..max -- new, filter by stripes for raid0/10/5/6
69 * limit=min..max -- enhanced to take range

71 inclusive as for the others, to keep the same behaviour as usage=N .
73 * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
74 * error messages updates, rewordings -- some fstests may break due to that
75 * added support for free-space-tree implementation of space cache -- this
76 requires kernel 4.5 and is not recommended for non-developers yet

176 aligned, it was incorrectly reported by fsck
