[PATCH v4 2/2] ocfs2: clear unaligned io flag when dio fails

From: Junxiao Bi
Date: Wed Jun 27 2012 - 05:11:20 EST


The unaligned io flag is set in the kiocb when an unaligned
dio is issued, it should be cleared even when the dio fails,
or it may affect the following io which are using the same
kiocb.
