Subject: [PATCH v4 07/27] xfs: get directory offset when adding directory name
Date: Fri, 21 Oct 2022 15:29:16 -0700 [thread overview]
Message-ID: <20221021222936.934426-8-allison.henderson@oracle.com> (raw)
In-Reply-To: <20221021222936.934426-1-allison.henderson@oracle.com>
From: Allison Henderson <allison.henderson@oracle.com>
Return the directory offset information when adding an entry to the
directory.
This offset will be used as the parent pointer offset in xfs_create,
xfs_symlink, xfs_link and xfs_rename.
