Subject[PATCH 5.9 119/757] crypto: algif_skcipher - EBUSY on aio should be an error
Date
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.

Fixes: dad419970637 ("crypto: algif_skcipher - Do not set...")
