Subject: [PATCH v3 18/26] xfs: Add parent pointers to xfs_cross_rename
Date: Wed, 21 Sep 2022 22:44:50 -0700 [thread overview]
Message-ID: <20220922054458.40826-19-allison.henderson@oracle.com> (raw)
In-Reply-To: <20220922054458.40826-1-allison.henderson@oracle.com>
From: Allison Henderson <allison.henderson@oracle.com>
Cross renames are handled separately from standard renames, and
need different handling to update the parent attributes correctly.
Signed-off-by: Allison Henderson <allison.henderson@oracle.com>
