      xfs: kill xfs_qmops · 7d095257
      Christoph Hellwig 提交于
      Kill the quota ops function vector and replace it with direct calls or
      stubs in the CONFIG_XFS_QUOTA=n case.
      
      Make sure we check XFS_IS_QUOTA_RUNNING in the right spots.  We can remove
      the number of those checks because the XFS_TRANS_DQ_DIRTY flag can't be set
      otherwise.
      
      This brings us back closer to the way this code worked in IRIX and earlier
      Linux versions, but we keep a lot of the more useful factoring of common
      code.
      
      Eventually we should also kill xfs_qm_bhv.c, but that's left for a later
      patch.
      
      Reduces the size of the source code by about 250 lines and the size of
      XFS module by about 1.5 kilobytes with quotas enabled:
      
         text	   data	    bss	    dec	    hex	filename
       615957	   2960	   3848	 622765	  980ad	fs/xfs/xfs.o
       617231	   3152	   3848	 624231	  98667	fs/xfs/xfs.o.old
      
      Fallout:
      
       - xfs_qm_dqattach is split into xfs_qm_dqattach_locked which expects
         the inode locked and xfs_qm_dqattach which does the locking around it,
         thus removing XFS_QMOPT_ILOCKED.
