| |
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jan Kara <jack@suse.cz>
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.
