btrfs-progs-4.7.1

[Douglas R. Reno]

New minor version

Hi,

btrfs-progs 4.7 have been released. Though it's a minor version release, there
are changes that could be considered big but I don't see a reason to hold them
until 4.8 is released.

There's expected bunch of bugfixes and improvements. The checker low-memory
mode has been in devel for a few releases, still needs some work, but releasing
it will allow for more testing. The improved error handling of mkfs/convert
should potential problems if the process fails in the middle and leaves a
partially created filesystem behind.

Tentative plan for the next development is to port reiserfs conversion to the
reworked convert and look again at the recent patchsets for dumping
extents/chunks or send stream.

Changes:
  * check:
    * new optional mode: optimized for low memory usage (memory/io tradeoff)
    * --mode=lowmem, not default, still considered experimental
    * does not work with --repair yet
  * convert: regression fix, ext2_subvol/image rw permissions
  * mkfs/convert:
    * two-staged creation, partially created filesystem will not be recognized
    * improved error handling (fewer BUG_ONs)
  * convert: preparation for more filesystems to convert from
  * documentation updates: quota, qgroup
  * other
    * message updates
    * more tests
    * more build options, enhanced debugging
