Subject: [PATCH v3 23/26] xfs: Filter XFS_ATTR_PARENT for getfattr
Date: Wed, 21 Sep 2022 22:44:55 -0700 [thread overview]
Message-ID: <20220922054458.40826-24-allison.henderson@oracle.com> (raw)
In-Reply-To: <20220922054458.40826-1-allison.henderson@oracle.com>
From: Allison Henderson <allison.henderson@oracle.com>
Parent pointers returned to the get_fattr tool cause errors since
the tool cannot parse parent pointers. Fix this by filtering parent
parent pointers from xfs_attr_list.
Signed-off-by: Allison Henderson <allison.henderson@oracle.com>
