92 People asked about duplicating data on a single device for a long time. There
93 are no technical obstacles preventing that, so it got enabled with a warning
94 about potential dangers when the device will not do the duplicated copies. See
95 mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
97 * support balance filters added/enhanced in linux 4.4
98 * usage=min..max -- enhanced to take range
99 * stripes=min..max -- new, filter by stripes for raid0/10/5/6
100 * limit=min..max -- enhanced to take range
101 Note: due to backward compatibility, the range maximum for 'usage' is not
102 inclusive as for the others, to keep the same behaviour as usage=N .
104 * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
105 * error messages updates, rewordings -- some fstests may break due to that
