Subject: [PATCH v6 6/7] generic: Verify if statx() can qurey S_DAX flag on regular file correctly
Date: Tue, 14 Jul 2020 17:40:08 +0800
Message-ID: <20200714094009.8654-7-yangx.jy@cn.fujitsu.com> (raw)
In-Reply-To: <20200714094009.8654-1-yangx.jy@cn.fujitsu.com>

With new kernel(e.g. v5.8-rc1), statx() can be used to qurey S_DAX flag
on regular file, so add a test to verify the feature.
