Btrfs progs release 4.7

Btrfs progs release 4.7

[David Sterba]

Hi,

btrfs-progs 4.7 have been released. There are several new enhancements, a
handful of bugfixes and other cleanups. The changes since rc1 are more fixes
for unaligned access on sparc64.

Changes:

  * convert: fix creating discontig extents
  * check: speed up traversing heavily reflinked extents within a file
  * check: verify qgroups of higher levels
  * check: repair can now fix wrong qgroup numbers
  * balance: new option to run in the background
  * defrag: default extent target size changed to 32MiB
  * du: silently skip non-btrfs dirs/files
  * documentation updates: btrfs(5), btrfs(8), balance, subvolume, scrub,
    filesystem, convert
  * bugfixes:
    * unaligned access (reported for sparc64) in raid56 parity calculations
    * use /bin/bash
    * other stability fixes and cleanups
  * more tests
