From c7da4ed95a78e38fdaffb06eaf1a3f3318b1add6 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Fri, 23 Dec 2011 11:53:07 +0100 Subject: [PATCH] udf: Mark LVID buffer as uptodate before marking it dirty commit 853a0c25baf96b028de1654bea1e0c8857eadf3d upstream. When we hit EIO while writing LVID, the buffer uptodate bit is cleared. This then results in an anoying warning from mark_buffer_dirty() when we write the buffer again. So just set uptodate flag unconditionally.
