From 13a8333339072b8654c1d2c75550ee9f41ee15de Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 30 Apr 2020 12:52:21 -0700 Subject: xfs: turn dfp_intent into a xfs_log_item All defer op instance place their own extension of the log item into the dfp_intent field. Replace that with a xfs_log_item to improve type safety and make the code easier to follow. Signed-off-by: Christoph Hellwig Reviewed-by: Brian Foster Reviewed-by: Darrick J.
