Subject: [PATCH v4 19/27] xfs: Add parent pointers to xfs_cross_rename
Date: Fri, 21 Oct 2022 15:29:28 -0700	[thread overview]
Message-ID: <20221021222936.934426-20-allison.henderson@oracle.com> (raw)
In-Reply-To: <20221021222936.934426-1-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>
