Subject: [PATCH v24 09/11] xfs: Add larp debug option
Date: Tue, 24 Aug 2021 15:44:32 -0700 [thread overview]
Message-ID: <20210824224434.968720-10-allison.henderson@oracle.com> (raw)
In-Reply-To: <20210824224434.968720-1-allison.henderson@oracle.com>
This patch adds a mount option to enable log attribute replay. Eventually
this can be removed when delayed attrs becomes permanent.
Signed-off-by: Allison Henderson <allison.henderson@oracle.com>
