From: Herbert Xu <herbert@gondor.apana.org.au> stable inclusion from stable-v4.19.153 commit b0112ecef7d8e65b71ee9e30d9635788ddcbb48b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6FMKH CVE: NA -------------------------------- [ 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...")
