From ed7ef8e55c6f24ae4347b5bda89e00af475ebc89 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Wed, 11 Jul 2018 22:26:17 -0700 Subject: xfs: remove unused btree cursor bc_private.a.dfops field The xfs_btree_cur.bc_private.a.dfops field is only ever initialized by the refcountbt cursor init function. The only caller of that function with a non-NULL dfops is from deferred completion context, which already has attached to ->t_dfops. In addition to that, the only actual reference of a.dfops is the cursor duplication function, which means the field is effectively unused. Remove the dfops field from the bc_private.a union. Any future users can acquire the dfops from the transaction. This patch does not change behavior. Signed-off-by: Brian Foster Reviewed-by: Christoph Hellwig Reviewed-by: Darrick J.
