Subject: [PATCH v22 14/16] xfs: Add delattr mount option
Date: Mon, 26 Jul 2021 23:20:51 -0700 [thread overview]
Message-ID: <20210727062053.11129-15-allison.henderson@oracle.com> (raw)
In-Reply-To: <20210727062053.11129-1-allison.henderson@oracle.com>
This patch adds a mount option to enable delayed attributes. Eventually
this can be removed when delayed attrs becomes permanent.
