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

84 inclusive as for the others, to keep the same behaviour as usage=N .
86 * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
87 * error messages updates, rewordings -- some fstests may break due to that
