Subject: [PATCH 27/34] xfs: devirtualize ->data_entry_tag_p
Date: Fri,  1 Nov 2019 15:07:12 -0700	[thread overview]
Message-ID: <20191101220719.29100-28-hch@lst.de> (raw)
In-Reply-To: <20191101220719.29100-1-hch@lst.de>

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.
