[xiakaixu1987@gmail.com]

From: Kaixu Xia <kaixuxia@tencent.com>

Hi all,

This patchset include random fixes and code cleanups for disk quota.
In order to make it easier to track, I bundle them up and put all
the scattered patches into a single patchset.

Changes for v4:
 -delete duplicated tp->t_dqinfo null check and allocation in one
  patch.
 -drop the first two patches that have been applied.

Changes for v3:
 -add a separate patch to delete duplicated tp->t_dqinfo null check
  and allocation.

Changes for v2: 
 -add the ASSERT for the arguments O_{u,g,p}dqpp.
 -fix the strange indent.
 -remove the XFS_TRANS_DQ_DIRTY flag.
 -add more commit log description for delta judgement.

Kaixu Xia (3):
  xfs: delete duplicated tp->t_dqinfo null check and allocation
  xfs: check tp->t_dqinfo value instead of the XFS_TRANS_DQ_DIRTY flag
  xfs: directly return if the delta equal to zero
