Subject: [PATCH 23/34] xfs: remove the ->data_dot_entry_p and ->data_dotdot_entry_p methods
Date: Fri, 1 Nov 2019 15:07:08 -0700 [thread overview]
Message-ID: <20191101220719.29100-24-hch@lst.de> (raw)
In-Reply-To: <20191101220719.29100-1-hch@lst.de>
Replace the only user of the ->data_dot_entry_p and ->data_dotdot_entry_p
dir ops methods with direct calculations using ->data_dot_offset and
->data_dotdot_offset.
