Hi Chris,

This is collection of some bug fix, enhance and cleanup from fujitsu
against btrfs for v4.5, mainly for reada, plus some small fix and cleanup
for scrub and raid56.

All patchs are in btrfs-maillist, rebased on top of integration-4.5.

TEST STATUS:
Tested by xfstests, btrfs and generic group with default mount option,
diffed result with 4.4-rc8 and confirmed no regression:
Diff From:
  dir=/var/ltf/testqueue/v4.4-rc8/xfstests/
  head=v4.4-rc8
Diff To:
  dir=/var/ltf/testqueue/8e16378041f7f3531c256fd3e17a36a4fca92d29
  head=v4.4-rc6_00037_8e1637
Test:
  node=ALL
Decrease items:
  none

Xfstests for other 9 mount options is in running, I'll check results after finished.

Would you please consider merging the following fixes to integration-4.5 branch?

REPO is:
