btrfs-progs-4.4 (2016-01-18)
User visible changes:
* mkfs.btrfs --data dup
People asked about duplicating data on a single device for a long time. There
are no technical obstacles preventing that, so it got enabled with a warning
about potential dangers when the device will not do the duplicated copies. See
mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
* support balance filters added/enhanced in linux 4.4
* usage=min..max -- enhanced to take range
* stripes=min..max -- new, filter by stripes for raid0/10/5/6
* limit=min..max -- enhanced to take range
Note: due to backward compatibility, the range maximum for 'usage' is not
inclusive as for the others, to keep the same behaviour as usage=N .
* manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
* error messages updates, rewordings -- some fstests may break due to that
* added support for free-space-tree implementation of space cache -- this
requires kernel 4.5 and is not recommended for non-developers yet
* btrfs filesystem usage works with mixed blockgroups
Other:
* installation to /usr/local -- this has unintentionally changed during
conversion to autotools in 3.19
* check: fix a false alert where extent record has wrong metadata flag
* improved stability on fuzzed/crafted images when reading sys array in
superblock
* build: the 'ar' tool is properly detected during cross-compilation
