Subject: [PATCH v14 14/15] xfs: Add delattr mount option
Date: Fri, 18 Dec 2020 00:29:16 -0700 [thread overview]
Message-ID: <20201218072917.16805-15-allison.henderson@oracle.com> (raw)
In-Reply-To: <20201218072917.16805-1-allison.henderson@oracle.com>
This patch adds a mount option to enable delayed attributes. Eventually
this can be removed when delayed attrs becomes permanent.
