Subject: [PATCH] UDF: Fix incorrect error handling in udf_direct_IO()
Date: Thu, 6 Sep 2012 11:08:11 +0100 [thread overview]
Message-ID: <1346926091-3654-1-git-send-email-abbotti@mev.co.uk> (raw)
In-Reply-To: <20120905190239.GK18051@quack.suse.cz>
My recent patch to add DIRECT_IO support to the UDF filesystem handler
contains a mistake in the error recovery if blockdev_direct_IO() fails.
The test `rw && WRITE` should be `rw & WRITE`. Fix it.
