From: Herbert Xu <herbert@gondor.apana.org.au>
[ Upstream commit 2a05b029c1ee045b886ebf9efef9985ca23450de ]
I removed the MAY_BACKLOG flag on the aio path a while ago but the error check still incorrectly interpreted EBUSY as success. This may cause the submitter to wait for a request that will never complete.
