Subject: [PATCH] crypto: algif_skcipher - EBUSY on aio should be an error
Git-commit: 2a05b029c1ee045b886ebf9efef9985ca23450de
Patch-mainline: v5.10-rc1
References: git-fixes
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.
