[GIT PULL] Fujitsu pull part1: cleanup

[Qu Wenruo <quwenruo@cn.fujitsu.com>]

Hi Chris,

Would you please consider merging the following fixes for your 
integration-4.3 branch?

https://github.com/adam900710/linux.git for_chris_4.3_part1_cleanup

Most of them are harmless cleanups, like removing unused 
parameters/judgment, or comment/variant name change.

We have already tested them for about 2 days, and it would be safe.

Based on 46cd28555ffaa40162290dba203daad0ff6f7abd.
And can be merged with pull from Filipe automatically without any conflict.

P.S:
Schedule for rest pull:
Part2: btrfs/070 fix.
   The patchset is already updated sometime ago, but we are using more
   test to make sure it won't cause any new bug.

PartN: qgroup reserve space leak fix. (maybe for 4.4)
   This one will involve some huge change in btrfs qgroup reserve
   mechanism.

   The idea is to keep a per-inode map for which range of space is
   already reserved, to avoid double reserve for same range but only
   freed once case.

   It's still under development, and it may not be able to meet
   current merge windows.
   So it's will be for 4.4.

PartN+1: Metadata and data qgroup support. (maybe for 4.4 with PartN)
   Some old patches from Yang, but needs some updates for new qgroup
   accounting/reserve mechanism.

Thanks,
Qu
