From e2950bf166ef71ed5588437b7ee94f65ceaa6cd0 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 16 Feb 2023 18:35:19 +0800 Subject: crypto: kpp - Count error stats differently Move all stat code specific to kpp into the kpp code. While we're at it, change the stats so that bytes and counts are always incremented even in case of error. This allows the reference counting to be removed as we can now increment the counters prior to the operation. After the operation we simply increase the error count if necessary. This is safe as errors can only occur synchronously (or rather, the existing code already ignored asynchronous errors which are only visible to the callback function).
