Subject: [PATCH 4.7 36/59] ubifs: Fix xattr generic handler usage
Date: Mon, 12 Sep 2016 17:29:56 +0200 [thread overview]
Message-ID: <20160912152130.284818105@linuxfoundation.org> (raw)
In-Reply-To: <20160912152128.765864031@linuxfoundation.org>
4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Weinberger <richard@nod.at>
commit 17ce1eb0b64eb27d4f9180daae7495fa022c7b0d upstream.
UBIFS uses full names to work with xattrs, therefore we have to use
xattr_full_name() to obtain the xattr prefix as string.
Cc: Andreas Gruenbacher <agruenba@redhat.com>
Fixes: 2b88fc21ca ("ubifs: Switch to generic xattr handlers")
