231 People asked about duplicating data on a single device for a long time. There
232 are no technical obstacles preventing that, so it got enabled with a warning
233 about potential dangers when the device will not do the duplicated copies. See
234 mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
236 * support balance filters added/enhanced in linux 4.4

240 Note: due to backward compatibility, the range maximum for 'usage' is not
241 inclusive as for the others, to keep the same behaviour as usage=N .
