From 787977215736e88b480044c2d4358a940b9879b5 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Thu, 4 Oct 2018 21:36:10 -0500 Subject: [PATCH] xfs: use internal dfops in attr code Source kernel commit: 9c6bb0cf7ba318767107328f39aac880344ddd2e Remove the unnecessary on-stack dfops structure and use the internal transaction dfops instead. The lower level xattr code already appropriately accesses ->t_dfops throughout. Signed-off-by: Brian Foster Reviewed-by: Bill O'Donnell Reviewed-by: Christoph Hellwig Reviewed-by: Darrick J.
