Subject: [PATCH] crypto: algif_skcipher - EBUSY on aio should be an error
Date: Fri, 31 Jul 2020 17:03:27 +1000 [thread overview]
Message-ID: <20200731070327.GA17085@gondor.apana.org.au> (raw)
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...")
