[GIT PULL] Fujitsu for 4.4

[GIT PULL] Fujitsu for 4.4

[Zhao Lei]

Hi Chris,

This is collection of some bug fix and cleanup from fujitsu against btrfs in v4.3,
the main patch is these 2:
 Fix lost-data-profile caused by auto removing bg
 Fix lost-data-profile caused by balance bg
It can solve the problem of 'lost all data profile by balance and auto-remove-bg',
discussed in btrfs maillist.

Plus some enhancement and cleanup in scrub.

Would you please consider merging the following fixes to integration-4.4 branch?

REPO is:
https:// github.com/zhaoleidd/btrfs.git integration-4.4

Custom tests are done for patch of "Fix lost-data-profile", and I have queued
xfstests(btrfs/generic with all mountopt) for this branch,
(need about 4~5 days), and no error found until now(1 days).

Thanks, I have these all queued up.  I verified the patches and
cherry-picked them, since Linus doesn't like to see github pulls, but I
do appreciate having them all in one place.
