Subject: [PATCH v2 02/18] jffs2: Remove jffs2_{get,set,remove}xattr macros
Date: Fri, 20 May 2016 13:14:19 +0200	[thread overview]
Message-ID: <1463742875-9836-3-git-send-email-agruenba@redhat.com> (raw)
In-Reply-To: <1463742875-9836-1-git-send-email-agruenba@redhat.com>

When CONFIG_JFFS2_FS_XATTR is off, jffs2_xattr_handlers is defined as
NULL. With sb->s_xattr == NULL, the generic_{get,set,remove}xattr
functions produce the same result that setting the {get,set,remove}xattr
inode operations to NULL produces, so there is no need for these macros.
