It probably would've been worth saying *why* these changes are needed.

Even though the patch is part of a patch set adding "backlogging support",
this grouping won't be visible in git log.

There's another reason however for the -EBUSY -> -ENOSPC change,
i.e. commit 6b80ea389a0b ("crypto: change transient busy return code to -ENOSPC")
