Subject: [PATCH 19/34] xfs: devirtualize ->sf_get_parent_ino and ->sf_put_parent_ino
Date: Fri, 1 Nov 2019 15:07:04 -0700 [thread overview]
Message-ID: <20191101220719.29100-20-hch@lst.de> (raw)
In-Reply-To: <20191101220719.29100-1-hch@lst.de>
The parent inode handling is the same for all directory format variants,
just use direct calls instead of going through a pointless indirect
call.
