From 7e8ae7bd1c5d806316e6b6403ac2dd0be7a1f82b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 8 Nov 2019 15:05:37 -0800 Subject: xfs: devirtualize ->data_entry_tag_p Replace the ->data_entry_tag_p dir ops method with a directly called xfs_dir2_data_entry_tag_p helper that takes care of the differences between the directory format with and without the file type field.
