Hello Darrick J. Wong,

The patch 33ba61292084: "xfs: connect refcount adjust functions to
upper layers" from Oct 3, 2016, leads to the following static checker
warning:

	fs/xfs/xfs_refcount_item.c:535 xfs_cui_recover()
	warn: passing freed memory 'rcur'

fs/xfs/xfs_refcount_item.c
   523                  }
   524          }
   525  
   526          xfs_refcount_finish_one_cleanup(tp, rcur, error);
                                                    ^^^^
Freed here.

   527          error = xfs_defer_finish(&tp, &dfops, NULL);
   528          if (error)
   529                  goto abort_error;
   530          set_bit(XFS_CUI_RECOVERED, &cuip->cui_flags);
   531          error = xfs_trans_commit(tp);
   532          return error;
   533  
   534  abort_error:
   535          xfs_refcount_finish_one_cleanup(tp, rcur, error);
                                                    ^^^^
Again here...

   536          xfs_defer_cancel(&dfops);
   537          xfs_trans_cancel(tp);
   538          return error;
   539  }
