From: Sam Gandhi To: linux-kernel@vger.kernel.org Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 646 Lines: 18 Hello, I have seen some file systems like jffs2/ext4 etc setup the s_xattr field in the superblock structure. But there are files systems that do not initialize s_xattr field in the superblock. Can someone kindly explain what functionality does s_xattr on super block provides? What kinds of things file system wouldn't be able to do if the superblock doesn't have this initialized?
